Well, I don't think you quite know the story. Especially since you would have been on the opposite side of the field. Many guys don't nod their head, they just talk to them, and some give them a thumbs up. The flag was waived off b/c the ready for play signal had never been given yet. He was offside and it would have been the correct call. There weren't anymore infractions b/c they actually started lining up correctly.
