The man on the left is in the appropriate stance for The Ox, which is a leading guard with two modes, Right and Left. In the right Ox, stand with your left leg forward, hold the sword with the grip near your head, held high on the right side, so that your forward point stands against your opponent's face. In the left Ox, stand with the right leg forward, hold the sword with the grip near your head and held high to the right, etc.
The man on the right stands in the correct stance for the Plough, which is also two moded, Right and Left, and is only for stabbing out from below. In the right Plough, stand with your right foot forward, hold the sword with the grip near your forward knee, aim the point at your opponent's face as if you wanted to stab it from below. In the left Plough stand with the left leg forward, etc., and hold it just like on the right.
