So the guy could have gone up to the girl and said, "Is this guy bothering you?" and then encouraged her to talk back to him herself. That's not nearly so stereotypical.
If I was a girl, I would find that overwhelming. Instead of unwanted contact with just one guy, I now have unwanted contact with two guys.
Plus, that sounds like a bad cop/good cop routine to use the first guy to make the second guy look like an attractive candidate for a significant other.

Maybe I'm just over-thinking this.
