Bug Ball clips into shooting star

After activating multiball a ball clipped into a shooting star that was already occupied, it didn't end well. This is the Mac version of the game, but it wouldn't surprise me if it could happen on any platform. I was lucky enough to be recording the gameplay at the time: http://youtu.be/5frbyKONarI

This has happened to me a few times in the PC version, although the balls might have been next to each other and both got caught. Very odd.
