You are correct. The problem is really semantical, for before the advent of AWD vehicles, there was the 4WD vehicle. The later when engaged usually with a floor lever or dashboard switch would operate with all 4 wheels turning and digging along. There were cautions that this system could NOT be engaged over 40 MPH or used on dry roads. I had a Pathfinder like this.
Then came the AWD vehicles that can be a simple breed that is FWD and waits for any detected slipping. Then it quickly tries to get the motion going again by engaging some power to the rear wheels. GM with is Vesa-Track is a prime example of this recovery AWD. It is is constant damage control.
The Rogue AWD is more complex and does not wait until things have begun to slip. This intuitive AWD has more complexity than the others and is more like the systems found on the high-enders like BMW.

Regardless of the system, once it is buried in deep mud or sand, you are done. That is why those winches are on those off-road vehicles. The Rogue does have a Lock Mode for its AWD that puts all 4 wheels into motion, but this is an emergency feature for crawling out of trouble and cannot be used over 5-7 MPH.
