On the jack stands the only the rear wheels will turn. Especially at idle speed you aren't going to trigger a sensor.

Pre x-drive (up through 2003) don't have sensors in the transfer case. In normal driving all wheels are powered.

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.

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.
