  NASes have always had "creative" interpretations of authorization
policies coming from an AAA servers.  So this behavior is well within
the traditional AAA.

  I agree.

  I would phrase the difference as being either the ability to *do*
something, or the ability to *have* something.  Items like "session
timeout" control the ability to have a session.  Once the session is
over, the ability goes away.  Other items could be allowed to continue,
even after the session has been finished.
