The transfer case will work like an open differential, so if there is a slight drag on one axle the wheels on the other axle will turn (ie at idle). But as soon as the speed differential is sufficient for the DSC system to apply a wheel brake on the spinning wheel, that will change. That is when the vehicle drives off the jack stands. I've been doing it this way my entire life on all wheel drive vehicles with not even the suggestion of any sort of problem. JCL you are well known for good advice on this board. I do find you rather condescending at times, And, on this you are over the top condescending.
It is dangerous to suggest that anyone work on an AWD vehicle with the front wheels on the ground and the rear wheels hanging, with the engine running and the transmission in gear. It is even worse to suggest that someone may get underneath that vehicle. Don't even try and justify that 'it will be fine'. It is simply a very bad practice.

At idle its going to drive off the blocks (note the front is level with the rear)? NEVER. if it scares anyone then block the front corners as well so the front wheels spin free. Getting under the car when the car/shifter is in
park is not dangerous; just because you wouldn't do it doesn't make it dangerous. read the entire thread for details instead of picking what you want.
