UNDERSTAND: Your leg turns as-a-result of your torso and waist turning into the right hand - your right hand is NOT a result of your leg turning, it's the opposite - thus, it is not imperative that the leg twists upon throwing your right hand - it is however important that as much of your body is delivered into the explosive right hand as possible - as a result, your leg may twist - be careful not to lunge too much into the right hand which may leave you off balance and vulnerable.
