Windows (Vista) User's Document Folder Names

Under Windows XP using Roaming Profiles and Folder redirection for the My
Documents folders, Windows creates a folder for each user under the specified
share on the server. This folder, together with the appropriate security
settings, was simply designated the users' name as per the %username%
variable. The result of which was a shared network folder with multiple
user's folders inside. As an administrator I could easily navigate to a
user's redirected My Documents folder on this share and view/modify files as
required.

Windows Vista seems to do something a little different; as before it creates
the relevant folder inside the share, but (somehow) they are all simply
called 'Documents' - you cannot tell them apart without going into the
Security tab of the Properties page and seeing which user the folder actually
belongs to!

The question is, how can I get Vista to propely name these folders, and also
how can multiple folders with the same name exist in the same folder!?

Just to add to the confusion I created a shortcut to one of the folders and
put it on another user's Desktop. Nothing about the shortcut suggests that it
would take you to the correct folder on the share, but it does! This tells me
that some element of Windows or NTFS 'knows' which folder is which and that
this non-unique naming is being done on some other display-only level.

Any help is greatly appreciated
