RFC 3264 doesn't describe PRANSWER.  The concept is entirely absent.

   The offerer MAY immediately cease listening for media formats that
   were listed in the initial offer, but not present in the answer.

"the" answer.

I'd be pleased if you could find something concrete that supports
this, because I just re-read 3264 and I can't find anything supporting
your conclusion.

I have no problem with the idea of a well-established status quo that
does not conform to the documents.  That would be consistent with many
other RFCs.  However, if that is the case, perhaps someone could write
this behavior down so that we can use the same definitions.  Clearly,
that isn't happening right now.
