Well it's not a TRUE reset, but it's a more bad ass way of setting up the whiff boomerang to trick them into leaving an opening for you. It's sorta a way to try and cheese out 2 2/3rds of a combo. vs 1 full combo. So it's sort of a trick to get ahead/catch up. where as doing the full combo is more safe/guaranteed to not possibly have you waste a bar of meter.
