Tough one, I'd say this is an incomplete pass. But like NVFOA_Ump said, a judgement call, which was discussed on the field, so if the replay didn't overturn the call, I guess I need to calibrate my judgement 
Pretty sure that was a HS game, so replay wasn't overturning anything.

That said, I also have an incomplete pass on this. If pressed for a difference between the two, in the MSU play, the receiver had the ball tucked with clear control and then separately extends the ball to the pylon. In the Navasota play, the ball is basically still moving in the same direction as it was passed - it seems to me the receiver doesn't have clear control.
But really, the honest answer is that this is a judgment call, and I'm sitting in my office comfortably looking at these plays on a monitor. I believe that my judgment on the field would be a catch in the first instance and incomplete in the second (regardless of whether or not the end zone was involved), but (a) I can't be certain of that because I'm NOT on the field, and (b) I'm certainly not going to substitute my judgment for that of the guy at the pylon. So,

it is.
