I don't think there's any need to apologize. The only shot I saw of this previously was a tight shot, where you can't see who's actually pulling. As the clip shows, Paul was crouching (standing) over the shoulder of the guy actually pulling, so you could have thought it was him from a distance-- but it wasn't. The guy to Olivia's right I'm guessing might be someone on the awards committee, as he presents the plaque immediately afterward?
Anyway, interesting to see how all the speculation went.
ADDED: Just viewed it again, and it's clearly the MC guy. He appears to be helping Olivia pull the string, so it was actually her and Dhani who revealed the star, and the MC helped get the cover out of the way and hand it off to the helper bee.
