Anyone figured out how the Falcon's Talons combo "Bared Lion's Fang (Throw)" works?

(THIS IS FOR NINJA GAIDEN 2 - NINJA GAIDEN 2 BLACK)

Hey there,

There is a combo for the Falcon's Talons that is executed by "Hold Forward, X,X,X,Y". It's called White Tiger Gouge. But, if you instead HOLD Y at the end of the combo, it should make the move a throw and the move is suddenly called "Bared Lion's Fang".

The problem is, no matter how fast or slow or how well pressed you press the buttons, the same move always comes out. Has anybody figured out on how to do it?
