No, this can be the case with all drive configurations. With overdrive at the front the front wheels turn faster than the rear. If using same diameter tires and off throttle, the fronts will want to try and spin the rear wheels slower thus creating more drag at the front end = more weight transfer to the front. This can the lead to oversteer off throttle.
The one way in this case doesn't help because the frnt wheels will be running at a lower rpm than the rears thus effectively engagine the one way all the time.
