Really for what? Apple Events are for interprocess or interapplication communication. I'm not a Carbon programmer. I am just curious why one would use Apple Events outside of making your app scriptable.

Well you have to use them to make your app recordable too, and RB is recordable. I didn't see the stack trace but in a recordable application it's sometimes considered good form to implement all actions by sending apple events to yourself and letting your apple event interpreter initiate the requested task. I don't know if that's how RB works but it would offer a plausible explanation.
