Situation #2 could fall under the same rule, but its something that will never be used. It's a tactic used very often and, while I don't like it, it's really no different that laying on the ball after a short run to make the official take longer to spot the ball, thus running the clock. They're all stall tactics, but seldom disciplined by an official. I have seen officials refuse the ball exchange, but never penalize a coach for trying. It's really up to the official to accept the new ball, thus becoming part of the problem and not the solution.
