I see a lot of the prevalence of trying rough stretches in normal mode as emphasizing that it's a full time four wheel drive (albeit with a strong front wheel drive bias) even in normal mode. I do think it's important to point out that even for offroad driving, the goat modes are mostly a "enable temporarily as needed" as opposed to "stop, put it in 4-high for the entire trail" like you would with a "normal" part-time 4WD vechicle.
Given the (very real, but over-emphasized) drawbacks of the PTU + rear clutch vs a transfer case + mechanical locker, you really don't want to lock things (either PTU or diff) for very long periods of time to avoid overheating. One big advantage of this system is that you can change "on the fly" without stopping for sections of trail where you're likely to need it and not lose momentum. If you switch it to rock crawl mode or mud/ruts mode and try to drive 20 miles in that mode, you're likely to overheat things. (Those are the two that lock the PTU and/or rear clutch.) Instead, leave it in normal for most of the trail and toggle it on when you get to a rough stretch. 'Course, toggling it on before you get stuck makes a ton more sense, and they never seem to do that in these videos...
Regardless, the roller tests are a really nice demonstration of how it all works and how the different modes affect things.
