That's a snapshot of a split second. I don't think we can arrive at that conclusion from this photo. Could have caught him in the middle of forming another expression. What's interesting to me is that he had someone on speaker phone and held it up so the person on the phone could hear and so the people in the room could hear what the guy on the phone had to say about it. And what he had to say about it was "THIS guy...knows what he's talking about."

That was some platinum grade hopium if you ask me.
