If you go with 2 motors on one axis, remember there are 2 kinds of stepper drivers. When you power up some will remember the last coil pattern used and some won't.

Doesn't make a Jot of difference if using Home switches which you really should use with Twin motors.
It's good practice to home the machine when first switched on and Most industrial machine won't let the machine function untill the machine as been homed. This ensures your setup and square so any step jumps on startup doesn't come into play.
It's also best to home the machine between every job if not shutting down just to remove any errors that may have crept in over period of the last job. This is why I prefer single motor/belts on machines that will be running single jobs for 12hrs +.
