That should clear it up. If the collision code is written so that you only collide on your PC and you can only take damage not give damage in a collision then it seems unlikely that a collision you didn't have damaged you. As far as I know that's how it works. Even without the collision message it should be clear if you hit or missed on your end.
That's how I've always understood it as well, and why this stood out to me.
I'll start going through films, and hopefully I'll find it.

Talk about spending time on doing something with no real world value!
