What causes the backflip rollover?

Was watching a vid of Jeep rollovers. I noticed a lot of them were backflipping when trying to climb an obstacle. First one in the vid is here, but I noticed multiple:

What are the main causes of these rollovers, locked rear diffs but open front? Too much gas at the wrong time?

To bridge the gap a bit, long arms in TJs tend to have low antisquat which makes the rear squat when you give it throttle. So you get up on a steep obstacle, give it a bunch of gas and the geometry pulls the chassis down toward the rear axle, then once the CG gets behind the rear axle... It's going over.
 
A few poor acceleration/ brake vs. clutch or neutral...then brake situations as well.
Saved myself a few times by giving preference to blind reverse downhill over blind forward up
It makes you wonder how many of those were autos. 🤣

Too much traction, too steep and too much gas. The suspension isn't a big part of it.
In my experience I've noticed that low antisquat is an issue that long arms exacerbate on TJ's. If the rear squats while climbing a steep obstacle, it throws the front rearward toward the tipping angle.
Slamming the gas pedal to the floor definitely doesn't help the situation either though 🙃

I don’t think this is mainly due to geometry issue, but the rear locker. It keeps pushing, and if you’re in an auto and don’t slip into neutral or a manual and don’t push the clutch you’ll keep going. Braking is a no no. Gassing it just exacerbated the problem. Going downhill is obvious. Getting sideways is dumb. Love how the dogs escape.
