Neither or them. It is simply the only expected behaviour.
Ethernet is simplex media, it does not hear itself and it is
impossible to talk to self using it. Well, if you do not believe,
try to use single phone to call to yourself.
Apparently you want to send to loopback. Continuing analogy:
to talk to self, you need not any phone at all and even better
not to strain tongue frightening people with selftalking. :-)
