One Step to Revenge, OSR

I've made this pattern incidentally while learning Rubenstein's Revenge. And really, later I've found there's only one step to revenge from this figure. Simply the green ball shouldn't be thrown crossing from one hand to another, but on the sides - making the throw under the hand.

How to do this pattern.

You must begin your training with two balls. Keep your hand crossed, suppose, the left under the right. Make a throw from the left straight up (blue ball in the animation), and with your right carry the ball (the red one) under raising (blue) ball and throw it outside and catch thrown from the left hand (blue). In other words, make an orbit around the blue ball with the red. Try it on both sides. When you've got this solid, juggle three ball cascade and try to make throw under the hand and making described gesture with another hand. Making it alternately on both sides you'll get OSR. The third ball (green) will take its part itself.

I'm sorry about my English if you had any trouble understanding this description. If you'll find any mistakes, please, let me know.
