Same as happens with conventional joined controls: you work out which one's working and use that.
Imagine a mechanical failure that locks both sticks!!!!
Breakout, like current designs.
Imagine a situation where the troop who has a good awareness of what the jet is doing and the other troop is clueless. Think AF447.
Good! You don't have to tell him to do something "stuff the nose down you moron!" you just do it; he gets feedback thru his stick and might even snap him out of his clueless state, esp if it jams his finger against the panel!
Asynchronous sticks are merely an engineer's preference. Uh oh, here comes Dozy...
