Rare people are capable of doing some pretty amazing things. Certainly telecommunication would be very rare but there is evidence all animals can communicate this way. We should have the ability as well but our development of the spoken language has caused this ability to atrophy. Some still have a strong empathy that can literally feel another pain or joy. Some people that spend enough time together get to the point that they communicate to each other without speaking. But this video would seem to stretch what is credible. But I don't see how anything he did, if he really did it, would be construed as cheating.
I've seen people capable of remembering multiple decks of cards in the order in which the cards were seen. That is not BS. Many do use his memory trick or other memory tricks to do amazing things.
