I am unsure about that guideline since I have never seen it. However the 
InitiateSystemShutdown API has a parameter called bForceAppsClosed with 
the following description:

    If this parameter is TRUE, applications with unsaved changes are to 
be forcibly closed. Note that this can result in data loss.
    If this parameter is FALSE, the system displays a dialog box 
instructing the user to close the applications.

(See http://windowssdk.msdn.microsoft.com/en-us/library/ms723171.aspx)

So the system can be rebooted or shutdown whatever the software running 
on it does. During normal system shutdown however the parameter is TRUE 
as far as I can see from the behaviour.
