It shouldn't but there are open diffs and not much resistance in the transfer case. So there really isn't anything to keep the car from moving when one or two wheels lose traction. The torque builds up to the point that one tire slips and it spins backwards as the others with traction rotate forward. Setting the parking brake should keep it from rolling.
Not saying that someone isn't fooling with you, but if the ice is slippery, it can happen even on a moderate incline.
