ICMP or UDP it matters not - the expected behaviour is that the return

Nope.
With ICMP the echo reply packet will have the source IP address
that was the destination address of the echo request.
With UDP the "port unreachable" report will tend to have the source IP
address of the interface on which the UDP packet was received.
Note well the distinction here. With ICMP you get a reply. With
UDP you get a non-delivery report. The distinction is important.
Test it. I did.
