If the driveshaft has the parking brake, it is possible to have the axle dis-engage and the truck roll a way all with the parking brake applied.
All in all it is best to park in low and leave it there.
The axle itself doesn't have a spring or detent to hold it in one position or the other. Vacuum and air shifter are spring loaded to the low position, air pressure moves the shift fork. Electric shifter use a torsion spring to pull the shifter to one position or the other, the motor winds up the tension on the spring, but it is the spring force that completes the shift.
Parking in low gives a driveshaft parking brake the best chance at holding. Shifting the position when not in motion, the spring may be wound up, but the load on the gears prevent it from shifting, until the truck gets bumped, then it may get stuck in between high and low.
