Pherhaps it was to spread the damage are because if you have 2 bomb on the wings and you release at a certain angles then the 2 bombs can cover 2 seperate areas whereas a single larger bomb cannot cover a wider area. Well it kinda can but if you are after more than one target than use 2 bombs because you can spread them out whereas one bomb is only good for target in a small area and you are kind of limited if you get what I mean.
