Does Profile Manger "Mobility - Account Expiry" work?

I've tested this a number of times and I've had no luck. I have a test computer setup and working with a PM Server and the client does pickup the updates in the profile but nothing happens. I've tested this by setting the "Delete mobile accounts" to hours and days with no luck. The users are logging in without an issue as a mobile user but their account do not delete.

Has anyone has this feature work?
