With the CR-V's system, tire condition shouldn't matter. All that matters is the difference in speed between the front axle (which is sent to the rear unit via the propeller shaft) and the rear axle. The propeller shaft drives a pump and the rear differential's pinion shaft drives a pump. The difference in speed generates fluid pressure which engages the wet clutches.
If the front tires were spinning and one rear tire was not, it's possible that the other rear tire was spinning, as it's an open differential in the back. If neither of the rear tires was spinning, then it either wasn't an AWD CR-V or there was a problem with the rear unit, which, though improbable, is not impossible.
That is certainly plausible but it begs the questions why not brake the wildly spinning tire(s) to get some form of traction.
If it was FWD I wouldn't bother mentioning it. I always look for a rear diff and associated markings.
Even some form of limited slip in that setup would prove useful too a point. My first Forester had no help. It only had LSD in the rear and like your MDX would fishtail if you gave it the beans. So it required more management than or current Forester which pretty much keeps you where ever the wheel is pointed.
Edit:
I agree with JHZR2 to a point, all things being equal I did fine with FWD and snow tires in my youth. AWD allows me to be...lazy about tires to a point.(not dumb though) It certainly is fun 4 wheel drifting in empty lots though!
