You could put the switch on the neutral wire and everything would work, but it would leave voltage potential to ground in the light when it is switched off. That makes it a bit hazardous for changing light bulbs. If you became an electrical path to ground through a wet floor or something you could get a shock.

If there is power in both the up and down position of your light switch, than that is the hot power. If the light was fed power first than here is how you connect the wires.

I normally use Green for ground, White for Neutral, Black for X, Red for Y (and orange for Z on an L21-30). On the Cal Standard plugs and connectors the X is colored Red and Y is colored Black.

Does it matter what wire goes where on a light switch?

There should be one wire only under each terminal. One of these will likely be black. The other may be black, red, or white. One of these is the power feed, and one is the switch leg, but the switch terminals are interchangeable, so there is no need to identify which is which.
