Because we are swinging on an inclined plane while standing "inside" of the Plane Line, the thrust has the appearance to our eyes of being "across" the Plane LIne. In actual fact, it is an "On-Plane" thrust and the club stays On-Plane.

To visualize this, imagine a golfer frozen at the Top of the backswing and you are on a ladder sighting straight down his Hands to the Ball. From your On-Plane vantage point, the line from Hands to Ball would not appear to extend across the Plane Line -- it would run directly into the Plane Line.

Great explanation, Bob! And a good visualization, too. Thanks!
