I agree with the sense of what you state below.
I have some nits with the words you use.

OK so far. But:

This depends on what you mean by "already in a bundle group".
Certainly they are already in a bundle group in the offer, so presumably 
that is not what you mean.

I presume you mean that they were already in a bundle group in the prior 
O/A.

I think this can be stated more clearly. How about:

The answer to an offer containing a bundle group may remove an m-line 
from the bundle group if (and only if) the address/port of the m-line in 
the offer is distinct from the address/port of all the other m-lines in 
the offered bundle group. When doing so it must supply a unique 
address/port for that m-line in the answer.

	Thanks,
	Paul
