Yeah, clearly a no-catch by rule. But it is a bit silly that if you are coming from outside the end zone and reach just the very tip of the ball and touch the white paint, it is a td no matter what happens after that, but on a catch there is a whole process to be completed if you are in the end zone.
I am pretty sure if he had caught the ball at the goal line with his feet just outside the end zone and reached the ball across and had it stripped out the same way, it would have been a TD, which is a little weird as far as rules go
