this is just a guess but maybe it's because the prop usually stops with one or two (3 bladed prop) sticking down anyway. In a 2 blade Warrior with a Lyc. O-320, it always stops with one blade at 5 or 6 o-clock from the pilot's perspective. So, if you're going to sacrifice the prop and engine anyway, why not at least have the engine available for a go around if you don't have everything nominal?
