Many peoples' responses don't appear to adequately address the OP's concern. Inoby observed the card-animation for his initial deal, and specifically stated that he saw a 'natural' three-of-a-kind.

Are you people claiming that the game selects six or seven cards at random, sorts them, and then animates the deal to give the illusion of natural pairs and trios? What possible reason might there be to do this?

I have observed nothing to substantiate such a claim, and have seen the cards dealt one by one and THEN been sorted every single time I've watched.

Please let me know if I'm off base, here, but it seems everyone is missing the point, and spouting BS....
