TCS operation in cross-axle hang-up and similar situations

In another forum there is a discussion on-going regarding the way Jeep Patriots and Compasses behave / should behave in a situation where only one wheel per axle has traction. There seems to be some confusion between what the manual says, how people interpret what the manual says, and real-life experience. From what I've read from the manual, the TCS should act in a similar manner as a limited slip differential, but one video of an FDII Patriot showed an airborne wheel spinning freely until the vehicle was put into low range.

Have folks over here tested their MKs performance in a similar situation? Even better, do you have video of it? If so, I'd love to hear about it!

I have been in situations almoust like this, but Compass was in both situations in some angle and simple gravity might have done the job...
But, to think of it, in one case there was a big bump on the "road" and I stopped one wheel on it, only two wheels touching the ground, sometimes three as Compass was just hanging there... So the gravity couldn't push me upwards onto that bump, when I went there. But it may have been just luck

Here's a video posted to "the other place". Several times you can see an airborne wheel just spin freely. I guess that talk in the manual about the TCS acting as a limited slip was just marketing BS.

Tony, that's not an FDII in the video. No tow hooks.

You can hear that its a Diesel, that means FD I and a 6 spd. It could have used some better tires and a running start too but that wouldn't change the wheel spin, just made it easier. Electronic simulation is never quite as good as the real thing.

Its never quite the same as the real one

I am quite well aware of what sort of vehicle is in the video, thank you. However, nowhere in the manual does it claim that "limited slip"-type performance is available only on the FDII. Quite contrary. Hence, the question in the first place.
