The owners manual explains it pretty good.

Taken from said manual:
4A (4X4 AUTO) - provides electronic control four-wheel drive with
power delivered to the front and rear wheels, as required, for increased
traction. This is appropriate for all on-road driving conditions, including as
dry road surfaces, but is especially useful on wet pavement, snow, dirt, or
gravel.
However, that doesn't explain HOW it works. It's been explained to me in this fashion:
4A engages the wheel ends, but not the front differential and/or driveline. There's been much debate on this cause as you said the truck shows the front driveshaft as engaged on the screen.

I had an explorer with this system and basically it will engage the front wheels anytime the computer senses slip in the rear wheels. I hated this system because mine would engage and disengage just turning corners in a parking lot with a little sand or taking off from a stop light on a slightly wet surface. Doing a nasty sounding clunk/bang every time it did it. I prefer my current system in my truck that I decide when to use. Mine does not have Auto4x4.

The AWD setting does supply power to the front axle, it uses a differential in the transfer case between the front and rear axle.
4WD in low and high range locks this differential together in the transfer case.

4A is basically 4X4 with the IWEs locking on demand.
In 4 A, the transfer case is locked, but the IWEs are not, so the front differential is free spinning. When the traction control system detects the rear wheels slipping it engages the IWE and you have 4X4, until it detects a possible bind then it releases the IWEs.
That is the way it was explained to me by a Ford rep at the auto show.
You can switch to screen 3 on the Gauge Mode in the instrument cluster display for the status of 4A.

Short answer is, it doesnt work very well. Seems like every vehicle ive had that has it , the 4wd tries to engage too late. Then I'm always guessing if its in 4wd or not.
Just put it in 4hi or 2hi. That way you know for sure what your in.
