Help with a High School rule

[Robert Goodman]

So the defender should try to shove the airborne receiver back but not hold on to him long enough to complete the tackle? And not to shove him across the sideline in the field of play either?

We know that if the receiver is carried off the ground out of bounds by an opponent after the catch, the pass is complete. No equivalent benefit if he's carried out of the end zone and dropped?
