Because some NATs would like to do port overloading, which is in
contradiction with these requirements. See section 4. of
http://tools.ietf.org/html/draft-ietf-behave-requirements-update-00 .
You're mentioned as an author on this draft by the way.
In this post I explain why port overloading can be somewhat desirable:
http://www.ietf.org/mail-archive/web/behave/current/msg10896.html
I make the same point across a large number of my posts.
