I always had the impression that 'nat=yes' is a bit of a legacy parameter
that carries back to a time when SIP signaling was not assumed to be
symmetrical, which was done later as a concession to the ubiquity of NAT.
In other words, a SIP UA was not necessarily justified in concluding that
the proper place to send a response to a client in dialogue was on the
exact same UDP port that the SIP request originated from.
