he is bending one note up, then releaseing it with out makein sound, and has another note prebent and then releases it down.

It sounds damn cool if you can get it right but obviously sounds completely different when PG and EJ do it. EJ does it with a quick bend up a slow release on the way down and PG has them just about the same.
