No!Micron Tx have always (as long as I can remember) allowed multiple Rx to be paired, but only the first of those switched on is actually connected, so you aren't running them all at the same time.
If you bind multiple receivers to the same (non-Selecta) transmitter, or the same Selecta position on a transmitter:
If two (or more) are switched on at the same time, they will ALL respond to the handset.
You can bind as many receivers as you like to a transmitter, but it is sensible to only have one model 'in steam' unless you are double-heading.
You can have Inertia AND Selecta (12 positions) if you wish:
