The video shows that the tire didn't come apart. It looks like the wheel came off with the tire attached. For just the tire to fall off whole, lots of bolts holding the two-piece rims together would have to not be bolted, and half the rim would come off, anyway, vs. one big nut holding the wheel to the hub.
Still, hard to believe either way: The wheel nut should have something like 250nm of torque, and it has a locking device, and swapping a wheel is a two-man job.

Accrual of under-examined metal fatigue likely occurred. This points to serious deficiencies in inspection.
