Anybody clear on Clampett's "Aiming Point"

[Scottgas2]

In "The Impact zone, Bobby Clampett stresses that to move the swing bottom 4" forward of the ball (?Low point?) is the Holy Grail of the golf swing. To facilitate this he uses the aiming point, a spot on the target line ahead of the ball towards which the hands should be directed on the down swing. When I set up with a wedge for example, even in forward press, there is no point on the plane line that intersects my eye and my hands which appear well inside of the plane line at address. Am I doing something basic that is wrong here?
