GPO "Limit the size of the entire roaming user profile cache" not working

This fix has been out for a few weeks, but for some reason I seem to have missed it. Allthough personally I have never had to configure this GPO setting, there has been released a bug fix for the setting "Limit the size of the entire roaming user profile cache". According to the KB, configuring this GPO doens't seem to work due to incorrect calculation logic.

Details below:

"Limit the size of the entire roaming user profile cache" Group Policy setting does not work in Windows Server 2008 R2

Consider the following scenario:
  • You install the Remote Desktop Session Host role service on a computer that is running Windows Server 2008 R2.
  • You enable the following Group Policy setting:
    Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Profiles\Limit the size of the entire roaming user profile cache
  • You configure some users to use roaming profiles when they log on to the computer.
In this scenario, the Limit the size of the entire roaming user profile cache Group Policy setting does not work. When the size of the roaming user profile cache exceeds the maximum size that you have specified, the oldest roaming profiles are not cleared. This behavior causes the roaming user profile cache to consume more disk space than expected.
