BUG ? Windows 7 Folder Redirection rename the Home folder in "My Documents"

Hello,
I experience an annoying behavior with the folder redirection with Windows 2008 R2 and Windows 7
i think this is a sort of bug.

Server : Windows 2008 R2 STD (US)
Station : Windows Seven (Fr)

We defined a hidden share as the home folder in Active Directory.

Ex :
\\Server\Users$\User1 (home folder for user 1)
\\Server\Users$\User2 (home folder for user 2)
Etc.

In my GPO:
When i configure the Folder redirection Setting with this parameter :
Basic - redirect everyone's folder to the same location
Redirect to the users home directory
Move the content of Documents to the new location
Also apply rediretion policy to windows 2000 etc...

When i log to the client, the redirection works well.

When i log to the server and browse my "users" directory, the user directory appear like he was renamed in "My Documents"

Ex :
D:\users\My Documents
D:\users\My Documents
D:\users\My Documents
...

The folder are not really renamed, it was just the display that was incorrect.

If i use a command line to browse the directory, the folder appear with the good name.
D:\users\user1
D:\users\user2
D:\users\user3
...

Someone can help to resolve this behavior ?
