Will the right wrist stop being level if the left wrist is cocked to 90 degrees or beyond? Is it possible to maintain a level right wrist if you allow the left wrist to cock to 90 degrees or more? Why or why not?

Thanks for the responses.

Try this.
Put both hands in front of you as if you were addressing a ball but with no club.
With palms together ,cock the left wrist.
Make your backswing to the top .Notice how the turning of the right arm enables the right wrist to remain bent and level-and it now matches the cocked left wrist.
