The rear wheels could be fully torqued while being held motionless with the E-brake, BUT the front wheels will just spin (the transfer case clutch is disengaged so the front wheels "freewheel") unless you have a second person in the car standing on the service brakes. However, it's never a good idea to apply a lot of rotational torque to a wheel of a vehicle that's supported on a jack. That rotational torque translates into thrust that tries to move the vehicle.
With the E-brake on, the opposite side wheel "chocked", and the tire loaded, you can safely torque the bolts on any wheel completely.

Makes sense.
