Jim, I'm not arguing with Mindy's text, and from the start the inside of the lead arm is directed outwards. This position will be held during the first part of the takeaway and could indeed be described as the arm is turning clockwise, but when the grip is secured (about when the hands have passed the hips), in order to close the clubface the right hand must go counter clockwise upwards, pressing against the lead thumb and thus creating "the good angle".
Perhaps I'm overcooking the pressure on the left thumb and the firm wrist traits, so I'd better check it out to see if there is anything that might come from maintaing the turned clockwise throughout the takeaway.
