This simple pulley allows the man to lift the box with less effort by reducing the amount of force needed to lift the box.

Yes, the pulley changes the direction of the force needed to lift the box. Instead of lifting the box directly upward with a lot of force, the person can pull down on the rope with less force and still lift the box due to the mechanics of the pulley.
