Same reasoning.

That way it gives the appearence of uniformity while marching. The command sequence for this: "If you are taller than the person in front of you, tap his shoulder and take his place." "RIGHT FACE!" "If you are taller than the person in front of you, tap his shoulder and take his place." Maybe there is a federal case for height discrimination? (Just kidding!)
