Semplicemente perché han capito Roma per toma. Il fix nel cumulativo è questo:

Addresses an issue affecting group policy expiration where an incorrect timing calculation may prematurely remove profiles on devices subject to the "Delete user profiles older than a specified number of day.”

E come indica chiaramente, riguarda appunto un comportamento anomalo con alcune specifiche policy, se attive (e di default non lo sono). Chi gestisce utenti su Windows server conosce quelle policy.
Il bug durante l'update è un'altra cosa e, come sappiamo, si verificava alla presenza della ridirezione delle cartelle utente in specifiche condizioni (come spiegato qui):
Quote:
This occurred if Known Folder Redirection (KFR) had been previously enabled, but files remain in the original “old” folder location vs being moved to the new, redirected location. KFR is the process of redirecting the known folders of Windows including Desktop, Documents, Pictures, Screenshots, Videos, Camera Roll, etc. from the default folder location, c:\users\username\<folder name>, to a new folder location. In previous feedback from the Windows 10 April 2018 Update, users with KFR reported an extra, empty copy of Known Folders on their device. Based on feedback from users, we introduced code in the October 2018 Update to remove these empty, duplicate known folders. That change, combined with another change to the update construction sequence, resulted in the deletion of the original “old” folder locations and their content, leaving only the new “active” folder intact.
Accordingly, below are the issues we have identified and fixed:
1) Using KFR the user redirected a known folder to a different drive. For example, suppose you ran out of space on your C drive. You want to save some files separate from your primary folder, so you add another drive to your system for these. You create “D:\documents” and change the location of the files known folder from the original “old” location c:\users\username\documents to D:\documents. In some cases, if the contents of c:\users\username\documents were not moved to D:\documents, then a user could also encounter this issue. When the October 2018 Update was installed the original “old” folder was deleted including the files in that folder (in this example c:\users\username\documents would be deleted; d:\documents, the new location, would be preserved).
2) The user configured one or more of their Known Folders (Desktop, Documents, Pictures, Screenshots, Videos, Camera Roll, etc.) to be redirected (KFR) to another folder on OneDrive. For example, the user changed the location property of the documents folder from c:\users\username\documents to another folder. During this process the system prompts the user and asks if they would like to move the files to the new location. If the files were not moved and the October 2018 Update is installed the original “old” folder was deleted including the files in that folder.
3) The user used an early version of the OneDrive client and used the OneDrive settings to turn on the Auto save feature. This feature turned on KFR for the Documents and/or Pictures folders based on the user’s choice but did not move the existing files from the original “old” location to the new location. For example, if a user turned on Auto Save for pictures the location of the Pictures folder would be changed from c:\users\username\pictures to c:\users\username\onedrive\pictures, but no files would be moved. The current version of this feature moves the files. If the files were not moved and the October 2018 Update was installed the original “old” folder was deleted including the files in that folder (in this example c:\users\username\pictures would be deleted; c:\users\username\onedrive\pictures, the new location, would be preserved).
We have fully investigated these issues and developed solutions that resolve all three of these scenarios, so the “original” old folder location and its contents remain intact.

Quando parla di "identified and fixed", non si riferisce al cumulativo, ma alla re-release del update fixata sul canale insider che adotta soluzioni per i 3 casi indicati nell'articolo:
Quote:
Today we take the next step towards the re-release of the Windows 10 October 2018 Update by providing the updated version to our Windows Insider community. We will carefully study the results, feedback, and diagnostic data from our Insiders before taking additional steps towards re-releasing more broadly.

Per farla breve, lo stesso giorno in cui hanno rilasciato il cumulativo per fixare una serie di bugs già identificati nella 1809, hanno colto l'occasione per spiegare cosa poteva provocare la cancellazione dei files utente e per rilasciare questa versione fixata dell'update 1809 sul canale insider.
Se tutto va bene, quella versione fixata passerà sul canale semestrale di win update (e come iso da scaricare col tool) per permettere a chi non è ancora passato alla 1809 di farlo.
Non so se ho reso l'idea ;)
