I'm guessing that the principle is the same - however not knowing much about golf equipment- I'd only guess that the actual COG of the Driver could be much closer to the face of the club than one would expect looking down on the club. In other words- looking down you might think it is "way back" in the center of the clubhead- yet based on the distribution of weight from front to back and due to the higher clubface versus the back of the club being lower or having less weight, etc. - that the COG may be a lot closer to the face and really not tend to close the clubface that much. Not sure that's right - just a guess. I do know that the question is a good one!
P.S. I just did a quck "longitudinal center of gravity test with a wedge and a driver i.e. lightly hold the grip with the forefinger and thumb and let the club "hang" vertically- and then see where the center of gravity passes through the clubhead i.e. the shaft line, the center of gravity of the shaft-head combo is surprising close to the top edge of my driver.
Although it would be good for an intelligent post to follow as opposed to this drunken guess that I've posted.
Did you have clothes on when you did the test retard?
