"Incline pushups? But, if your feet are elevated wouldn't that make it a DECLINE pushup?"
It depends on which perspective you look at it from. If you are looking at it from the exerciser's perspective, then it would be a decline because the torso slopes downwards (body declines).
Problem is, we don't usually look at movements from the exerciser's perspective. We usually (there are exceptions to every rule) look at movements from the ACTION'S perspective. During the action of the incline pressing motion, the arms are pushing up and away (superiorly) from the shoulder line towards the head. If you inverted the body and placed dumbbells in the hands of someone doing incline pushups, you'd see the exact same ACTION as an incline dumbbell press. Therefore, we call it an Incline Pushup.
