Remote Desktop LogonType

Hi..
In win32_LogonSession Class in Wmi.
http://msdn.microsoft.com/en-us/library/aa394189.aspx

for Logon Type parameter value is 10 then user logged in as RemoteInteractive
http://www.windowsecurity.com/articles/Logon-Types.html

But when ever connected by system using Remote desktop..the Logon type value is not changing ..it always returning some 5 values like 2,3,3,5,11..

What is the problem..Win32_LogonSession class always give some history data or the data will dynamically change ...

Thanks in advance...
