To hit down on the ball, rather than scooping, the grip of the club must pass the ball before the clubhead as you swing through the ball. Think of your swing like a bicycle wheel. Your hands are the hub, the rim is the club path, and the spokes represent the shaft. Where the spokes are angled to the rear from the hub, the rim is moving downward, and where the spokes angle forward, the rim….upward. So, if your hands go through the ball before the clubhead, your “spoke”, or shaft, is angled the correct way–to the rear– to assure a downward impact, assuming correct footwork.
