According to the NEC (National Electric Code) two or more motors are permitted on a single branch circuit if each motor has its own overload protection.

Of course you can provide an outlet near the saws at operating height that is on a cord plugged into the ceiling outlet. Then, to be correct by the code you would only plug in one saw at the time.

Multi-motor connections on shared circuits are generally permitted only if the motors are under 1hp.

I haven’t dug through the whole code on this and there may be exceptions, but I generally just put a fused disconnect on each machine and then they can both be wired together.
