NFL Touchback on Punts

[Bullycon]

My coworker had this question about the Colts-Chargers game and I wasn't sure exactly what the answer was.

On the Chargers final punt of the game, he believes that the Chargers player gained control of the ball while airborne, and that his foot hit the pylon before any part of his body hit the ground.

Now, I don't remember the replay of this punt, so I don't know exactly what happened. Just going by the one fuzzy video I saw on YouTube, I don't think he's right, but whatever. So forgetting the actual play, if the above scenario occurred, what is the ruling? Touchback? Or Colts ball on their own 1?

For the purposes of this discussion, the ball never breaks the plane of the goalline. The player never touches the ground in the endzone. The player jumps from the field of play, recovers the ball in the air after it has touched the ground at least once, and before he lands in bounds or out of bounds, his foot touches the pylon.

On a side note: I am correct that in both NFHS and NCAA the ball is dead at the point where it is recovered, 1st and 10 from the 1, right?
