When connecting homing switches, should I use more than one input?

It is ok to connect the limit/homing switches to the same input. The machine will go through a procedure that will start with the first axis, hit the switch, pull off, move more slowly for better accuracy, then pull off again. This procedure makes sure that the input is always in the correct state while homing. Additional Information: Is it possible to have proximity switches I use for homing connected to one input too?
