Wrong. Not that it matters one iota, but he is holding the ball correctly for a right-handed person.
His left hand should be more towards the middle/upper side of the ball and his right elbow should be be underneath it.
To be fair, I almost get the impression that he's getting ready to attempt spinning the ball on his finger the way his fingers on his left hand are spread and his right hand being too far under the ball.
