during bind it IS. the RX talks to the TX to know what modulation it's on. but to each their own.
No you are quite wrong.
You can even bind multiple RX's at the same time. Try it and you'll see.
Even under DSMX the bind is a unidirectional process.
People often mistake "model match" to be a bidirectional thing, as you've done.
