From the help file, nothing made me think that this was by design. If I scatter my way out of combat, then the combat is stopped. In case A, this is normal, when I am alone. In case B, the mob I'm fighting as part of a group re-directs onto another group member. Note that I'd expect this to happen if it were aiming at me, but it happens even otherwise.

I'm with GuyA and GuyB. GuyA takes blows. I scatter. Mob screams (yells) and attacks GuyB.

I think that's buggy.
