No if you do this step you will be doing the same thing you do with a straight right to the head but because your going low down with the shot the back foot being left behind will cause the exact same problems and exagerate them as you will find yourself leaving the back foot even further behind than you would with a straight right to the head. let your knees take you down with the shot rather than bending at the waist and reaching, try and make sure your right heel is under your ass as much as it can be, scrap used to say to me on these forums in a way what is more simple to understand is if your heel had an eye make sure it can see the target its aiming for and the line of sight isnt blocked by your ass. this will enable proper range and the ability to drive through with the shot if necessary.
