That seems like a pretty huge "mistake" to make. It's not like he stumbled over words or anything either at all. He was quite concise in articulating what he very clearly meant. I'm calling bullshit. With something like that there's no way you wouldn't catch yourself slipping like that — and you'd most certainly correct yourself immediately. Even a staff member would say something as you left the podium and you'd pop back over and correct the statement. I don't buy it.
