What does this block do?

I'm not sure, but I think it means the direction the sprite is being pushed by the image recorded by the webcam. For example, if you made a circle as a sprite, and put this script:

when green flag clicked
forever
if < (video (motion v) on this sprite > 10 >
point in direction (video (direction v) on this sprite)
move 2 steps


If you would touch that sprite from the left and push it, the sprite would move 2 steps in the direction it is being pushed (right).
