AWD uses either clutches or viscous fluid to transfer power front to rear and the clutches or fluid will automatically slip to allow power to be transferred front or rear without your input.
Full time 4x4 is totally different, it has gears in the transfer case and those gears only lock together if YOU lock them together, if not then it is a open diff which sends power to the path of least resistance.
When you lock your CDL YOU are literally moving gears inside the transfer case to a different position.
jycsalas has a great video of the inside of a Rover t-case with the inspection cover removed and the truck up on a lift while his girlfriend shifts into drive, reverse, and works the CDL but I cant find it.
You can see the gears moving, the CDL changing gears, etc.

And I mis-spoke, see https://landroverforums.com/forum/di...aft-out-43160/, it was not Spike, but some one else who's opinion I trust.

The transfer case has to be engaged in a minimum of H for the truck to move. Dont confuse the "diff lock" with the actual transfer case gearing selector. The transfer case has 5 possible modes of operation:
Hi Range (H)
Hi Range (H) with diff lock
Neutral (N)
Lo Range (L)
Lo Range (L) with diff lock
If you put the transfer case in neutral no drive at all will be transmitted from the output shaft of the transmission through the transfer case to the drive shafts. If you engage the diff lock then it locks the differential in the transfer case forcing both the front and rear output shafts to move regardless of being loaded or not and will allow you to limp home with a busted drive shaft or axle.
