Legally speaking, it is. Not that it is a real issue in practice.

Nup. It's diversity. Transmit and receive is always done on the same antenna.
Whichever antenna gives the highest receive signal strength, that is the one
used.

Again, those two antenna outputs are NOT TX and RX. They are simply two choices
of antenna for the radio to use for communication, e.g. in case one antenna has LoS
to the other node the other antenna doesn't.
If in doubt, check the circuit diagrams around on the net.

This is a common misconception, and I'd hate to build a rig just to find things
don't work the way they've been reported :)
