In this instance Asterisk will receive multiple responses for the single Request that are differentiated by the Via header.  This is something I am not proposing we do anything about at this time.

The via header will be the same, the one that you sent. The to: tags will be different.
This is not only in stateless mode, it can happen if two people answer at exactly the same time. The proxy can't cancel when it receives two 200 OK, but will forward it to you. It's a common SIPit test.
