Looking for a solid golf training aid? Moving further in to Tiger’s torso, we get very close to the prime cause for this around motion, his shoulders. The dots in the figure above right represent the positions of the outside edge of Tiger’s left shoulder from the top of his backswing to his finish (nearly-overhead view).
Connecting the dots in both these figures creates circular, round pathways--most certainly not a ‘forth’ oblong pathway.

To belabor this oh-so-important point, please look at the photos on the next page. The selected photo for each pro is that one in which the clubhead is shown farthest in the horizontal direction from the ball as represented by where the red lines hit the ground. The toes of the pros’ shoes are 32-34 inches from the ball, their shoes are about a foot long, and you can see based on the vertical red lines that most of the clubheads are another 12-15 inches behind the heels of their shoes.
Just look at how much grass is between the ball and where the red lines hit the ground-- about 5 feet. That omnipresent, two-dimensional face-on view not only gives a back-then-forth impression, it also makes the act of hitting a golf ball appear to be very up-down-up, or vertical. While up-down-up is important, a feeling of torso rotation should predominate.
