Folder Redirection Policy is never applied completely?

I'm using Windows Server 2008 with all current patches. I set up Folder Redirection policy. It seems to apply correctly. All the folders are created on my file share, and all local folders are now redirected there. And I see no warnings or errors in my event logs... in case I do not run gpupdate /force.

Every time gpupdate /force is run I receive the following message:

User Policy update has completed successfully.

The following warnings were encountered during user policy processing:

The Group Policy Client Side Extension Folder Redirection was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance.

Computer Policy update has completed successfully.

For more detailed information, review the event log or invoke gpmc.msc to access information about Group Policy results.

Certain User policies are enabled that can only run during logon.

OK to logoff?. (Y/N)

And then I receive the same message in my System event log.

And the following message in my Application event log.

Folder redirection policy application has been delayed until the next logon because the group policy logon optimization is in effect.

If I log off and log back on, everything works still fine. Just untill I run gpupdate /force once more. Every time I run it it brings me those messages. I see no more errors or warnings. 'Microsoft-Windows-Winlogon/Operational' event log is completely empty. 'Microsoft-Windows-GroupPolicy/Operational' contains only informational messages with one exception:

Log Name:      Microsoft-Windows-GroupPolicy/Operational

Well, it does not seem like something unexpected. Why is it marked as warning, not informational message?

KB305293 states that you receive 'Folder redirection policy application has been delayed until the next logon' message when folder redirection policy is not completely applied. So does it mean that my policy is never applied completely? What could be blocking it? How do I find it out? Or is it just an expected behavior in case of running gpupdate /force?
