How about in a dual com situation, tx on com1 and rec on com2?

I believe Jose's (revised ) observation still holds. If COM1 is
transmitting, and COM2 will receive the most powerful transmitter, then in
the case of the airplane transmitting that would be COM1, not someone else
telling them to unstick their mic.

And in fact, that's the only reasonable interpretation of what Jose wrote,
since the only receiver available to receive when the transmitter on one is
stuck is the other. Reception is automatically disabled when transmitting
for the transmitting radio, so it wouldn't receive the other pilot's
transmission in any case. (All this assumes exactly two radios, of
course...a common enough configuration).
