7th edition.... i have read this over and over and alwways thought this sounded wierd. "with true throw-out action (no manual clubface manipulation), centrifugal force automatically aligns the clubshaft and clubface for horizontal hinging, regardless of grip being used. ball position for straightaway flight must agree with the amount of hookface designed into the club and is therefore unalterable except with manual override action or adjustment of the plane line. true "throw out" action holds the clubface in impact fix alignment and automatically produces angled hinging, regardless of lag loading procedure, vertical hinging is a deliberate manual manipulation."

so it seems that for centrifugal force he describes it as throw-out action
and for linear force application he also describes it as "throw out" action, maybe referring to the right arm throw making it still a THROW out action but to use the same words is a mistake. i realize this is not homers original verbiage

Please see post #9 in this thread. I thought your question looked familiar!
