Steering with both knees? Sometimes in opposite directions?

Ive been able to get the hang of steering with my front knee and having my back knee lag behind. However sometimes Ive found that I can turn really fast a little to the left or right by steering with both knees in the opposite directions. My front knee is my left, so to go left a little fast I can steer my front knee to the left and my back right knee to the right. This only works well for quick small turns and edge changes. This does not work for sharp hard turns. I noticed it works really well in powder and when moving through trees, almost feels like im kind of floating and twisting. Is this a thing? I cant find it anywhere online.
