Depends on the rule code. For ASA, a player can stand on a collapsed fence and make a legal catch:

RULING: Legal catch, the ball is live. (1-CATCH/NO CATCH-A[2]). Also see rule supplement "Falling over the fence on a catch"

However, NCAA and Fed both treat the bottom of the fence as a "out of play line"

Home plate, the bases, foul lines and poles are considered part of fair territory. Additionally, see AR 12.12.5: (snipped) In establishing "over the home run fence" on a collapsed fence, the plane is established from the base of the fence on the ground to the top of the fence when it is correctly positioned, not the top of the fence as it is falling or has fallen away from the field.

(sorry for not having a NFHS reference)
In both NCAA and NFHS, you can make a catch while crashing through the fence, but you cannot be on the ground beyond the fence line. I believe the first PGF championship game had this in question.

In all codes, the play in the OP (which is shown on the facebook video), should be ruled as a catch and carry. The fed rule was provided Ernie in post #14; NCAA 9.3 Note 5.
