I've been intrigued by this question too, but i don't think so. I believe the low range planetary is actually a center differential. With the 4410's, you had a center differential (planetary gear set) and a viscous clutch. I think the current AWD they keep the diff and replaced viscous with a shift motor or a magnetic clutch. With the 4WD and shift motor you don't need the a differential planetary so it becomes a low range planetary. Only way to know for sure is to get a service manual or break on down. This way the AWD transfer case can hook up to stability control which will engage 4wd to help control the vehicle. so the theory goes.
One way to test is to get all 4 tires off the ground, put it in gear. On my AWD 4410 all tires start and spin at the same time. I'm guessing the 4wd the rears would start to spin (about a half revolution or so) then the fronts would kick in.
