Actually, there's no reason that the image is nessicarily upside down, as the orientation depends on the location of the viewer on the earth's surface.
Imagine that where you the event appears near your horizon. Now, imagine someone else standing on the other side of the planet, though far enough forward that the moon is above their horizon. Now, from your viewpoint, the guy on the other side of the world is nearly upside down reletive to you, so he would see it as upside down relative to you. Also, he'd see it on the opposite horizon - that is, one of you would see it on the east horizon, the other on the west.
You could also see it from any other angle - e.g. the guy standing on the north pole looking south sees it as rotated 90 degrees sideways from someone on the equator.
