I know the guys at the NTSB have their hands full and wish them all the best in finding the cause of this accident so we can all learn from it.
No one does that on the 767. If you want to go down fast you simple select flight change and the throttles go to idle. If you want to help you can pull them to idle however the auto throttle system is still connected and will add power to maintain speed at the level off. I never saw the technique you mentioned used even once in 15,000 hours on the aircraft.
