I wonder about this too. During all of my PE classes in elementary and high school a pushup didn't count unless your nose touched the ground and you came all the way back up. Pushups I see all over the place now, from tv shows to YouTube videos to folks in the gym are incredibly shallow, often only dipping down a few inches from the top position. Just as pullups and chin-ups are different things, perhaps these shallow pushups should have a different name to distinguish them from "to the floor" pushups.
