Wouldn't it be easier to visualize a right arm/wrist karate chop? That way the right arm is used for clubhead control and the left hand for clubface control. Clear and distinctly different roles. Another aspect of the left hand karate chop that confused me was that it placed clubhead control onto the wrong arm. Think about the bent back right wrist doing a karate chop motion with the right palm face up to the inclined plane.
