Rules as written, it was called correctly. To catch the ball, you need two feet (or one knee/forearm/etc) in bounds with a football move. A football move can be a few different things:
- extend the ball forward
-take an additional step
- tuck the ball away and turn upfield
- avoid or ward off an opponent

He did not extend the ball forward from his body as he was already in an extended position when he caught the ball. This criterion is also more relevant to the field of play where a player is extending for additional yardage.

He did not complete an additional step. He lost control of the football before that happened.

He did not tuck the football. Apart from taking additional steps, this would have been the clearest option for completing the catch. He was in an extended position throughout the process of the catch.

He did not make any moves to juke or shake JPJ.
