GTA: Why does the moon change size when you snipe it?

This went on a bit and I suggested to make the size of the moon changeable in the game. This way they could decide in their own time and let me know the conclusion. Since I was working on the sniper rifle, I made it so that the moon toggled through 3 sizes (small, medium, large) as the player sniped it. The artists never got back to me so I just left it in. It was still there in SA.

I guess everyone runs into situations like this!
