I thought about it some more and came to the conclusion that for a B2BUA
it does seem legit to accept the first codec in the reINVTIE's offer and
use transcoding to make the bridge work. It's not what I would like to
happen, but that's a different story :D

I also found a posting from 2011 which mentions this behavior:

Anyway, "case closed".
