Right, you're wrong.
The rear locker is actuated seperately via a button, it's operational only in 4-lo. It locks the rear differential.
The transfer case, which distributes power to the front axle and rear axle, has it's own differential of sorts. Unlocked (aka full-time 4wd) it distributes power 70% to rear, 30% to front and allows slippage. Locked (aka part-time 4wd) is just turns front & rear axle irregardless of either axle having traction or not.
It's really quite simple once you get beyond the confusing issues.
One thing I will say, it's important to know and fully understand these features and how they work when offroading. More valuable then most realize.
