Yes, the defender can grab the receiver after the ball was tipped, but that does not include holding when they both are on the ground and the one tries to scramble for the ball.

The Mooney defender did not at first commit the pass interference. He drew the flag when he grabbed the arm of the receiver while both were on the ground and the ball still in the air keeping the receiver from getting under the ball and possibly making the catch. Watch it again. You will see it.
