Dogs react strongly when people start jumping or running around or taking their stuff. That is the teasing, and then wagging the tail and other playful signals makes it playful teasing rather than aggressive. I don't see how this is any more standard protocol than humans teasing each other. They do something to trigger the other person and then signal "just kidding!".
