I have not watched the attached video, but I am familiar with the event.
Heavily bogged, lifted full size 4x4 pick up that they attempted to rececover with a similar vehicle using a severely dropped (10" or so) receiver ball mount. Due to forces imparted during the attempted recovery the principal tube of the hitch failed and was torn away becoming a fatal projectile.
I have personally seen a similar failure only with a bed mounted gooseneck ball being the failure point and without subsequent death.
I'm not going to argue the viability of a properly mounted receiver hitch as the foundational recovery point, but I will say that nothing designed and engineered specifically for towing is acceptable as a recovery point, and the habit of using a cross pin only with a strap isn't much better.
