I think there's a variety of reasons.

First, they look bog standard, so there aren't going to be things like longer shackles, lift kits, bad welding, bigger wheels etc. to cause things to go wrong/break mechanically.

The terrain doesn't look too harsh, they're just being aggressive.

They look to me like pay and play, rent-a-crash Vitaras so they don't care too much if they break 'em.

They were possibly lucky on a few occasions.

And finally, they probably didn't show the bad stuff if there was any.

lol, ill let ya know, im going there next week in a Jimny

They are going pretty steady.

Although i have seen people pop shafts at very low speeds.
