I am pretty sure that is just Mark Bell messing with people. Those are 45lb bumber plates. This would make his raw bench into the 800s, which I know isnt true.
The head up thing is kind of used as a rebound effect, most will drop their head some after they touch. Shirt benchers do it a lot to help get weights down.
