If you place an object on a flat surface:
1. It's weight + gravity will hold it in place.
2. It will float away
3. You have to tie it down somehow.
Your foot on the rear, rising bicycle pedal is the same. If you don't tie it down in some manner, you have to push on the upward rising pedal and you're working against yourself.
