I agree with you - the left shoulder must be well forward at impact to have a low point somewhere near the inside of the left heel.

Different golfers get the left shoulder to the "correct" impact location via different mechanisms. A S&T golfer, who has a small amount of left spinal tilt at the end-backswing (leftwards-centered swing style), will have to move the left shoulder far less to get the left shoulder to the 'correct" impact location than Tiger Woods, who has a rightwards-centered swing style.

By the way, I have altered the Tiger Woods photo by adding dotted yellow lines to demonstrate that the radius of the circle increases while the center of the circle moves leftwards/upwards/backwards.
