Is Regis 'green screened' in this Super Bowl commercial?

Just like the Coke employee trying to sneak one past everybody in this spot, Pepsi Max might be trying the same. I couldn't help but notice the odd outline of Regis as he enters the scene. And the odd relationship to the people behind him.

I'm not a betting man (which is good around the time of the Super Bowl) but I'd bet money he was shot a different time at a different location. Pepsi's hoping we won't notice the difference. C'mon Pepsi - we know the real thing when we see it.
