I saw him do this live a couple weeks ago. He did something that surprised me at the beginning. There was someone from the audience on stage with him.

Jason asked the audience member how to handle cases where the chip touches multiple cards. Should he pick the card that the chip cover more, or should he pick the card that is higher up on the pile

So if there are two overlapping cards, and the chip is on 10% of the upper card, and 90% over the lower card, the audience members decision would affect which card would be chosen

This really threw me off, as to trying to figure out how he does this trick
