That's what I needed to know. You should stop doing that. I was hoping that the drills I wrote for you would make it clear how the Right Forearm Rotates. Now I'm stuck because I can't find any sequenced pictures to show you.
One last drill to help your understanding of the Right Forearm motion and then I'll leave you alone.
You need a Bucket and fill it part way with water for weight. From Release to Impact, the water in the Bucket stays level. Grab onto the Handle with your right hand and bend the Right Wrist. The Handle will settle into the Fingers of your Right Hand. Travel from Release to Impact by pointing your right Forearm from out in front of you, to pointing mostly to your Left. The rotation of the Handle goes from Parallel to the Plane Line to Perpendicular to the Plane Line at Impact without "Twisting" the Right Hand.
