As wind approaches the leading edge of the sail, it separates and flows along both sides of the sail from luff to leech. The air on the windward side reaches the leech first, since it has a shorter route to travel.

Moving the block forward pulls the clew downward more than back, tightening the sail's leech more than the foot. Moving the block aft pulls the clew back more than down, tightening the sail's foot more than the leach.
