What about:

   The answerer MUST select the "m=" section *in the answer* that corresponds to the
   selected offerer tagged "m=" section in the corresponding offer
   [Section 7.3.1] as the answerer tagged "m=" section.  In the answer
   the answerer BUNDLE-tag indicates the answerer tagged "m=" section.

I can do that.
