It just means that you can drive in high range with all power going to the rear wheels and then have the benefit of the front wheels kicking in once wheelspin occurs at the rear. The only downside to this is driving in the sand as by the time the front kicks in the rear may have already dug in and you're going nowhere. This is not often though and you just need to know when to change to Low range to lock the centre diff. This only really needs to be done in the softest sand, but you can get away with at least 60km/h in Low range anyway, so if you're unsure, just use Low to get through the tough stuff.
I have a 4.7 V8 Limited with QT2 and I'm also a complete novice when it comes to sand driving and I got away with driving all over Fraser Island for a week without a drama. I did have one blonde moment when I left it in Full-time 4WD in a soft section at Orchid Beach servo and got bogged within 10m of the bowser, but after clearing the rear wheels of sand and popping it into Low range with the engine off, I just drove straight out. When I first got there I started off driving everywhere in Low range accept for the main beaches and then I realised that was overkill and pretty much drove everywhere in Full-time 4WD from then on.
You really will be surprised how well they go off-road even in standard trim and they love the sand too!!sigpic

This is operated by a gerotor pump, similar to how the QD diffs work.

Agree with Hanna - if you are new to driving your WJ/WG in the sand start in low range. Then find some soft-ish sand and then have a bit of play taking off from a standing start in full-time 4wd. You'll soon get a feel for how rear wheels spin a bit before the front wheels kick in.
The other issue, when stock, the transfer case is a bit lowand will act as a bit of a plough through the larger sand ruts. Trick here is just to keep your momentum up when it starts to drag a little. If you have a 2" + lift the problem goes away - it is I think just that the WJ/WG is a bit lower that most of the other vehicles around.
Other standard tricks are lowering tyre pressures and having a decent shovel.
Have fun
