Any idea what the flood illuminator does? It must help Face ID work in the dark? It can't be a flashlight that blinds you in the middle of the night, can it???

There will be no flashlight illuminating your face. That demo surely caused some confusion. Face ID sensors are advanced enough to see in the dark without any illumination.

The demo certainly made it look like a light shining on your face. Looking at the sensors on front the "Flood Illuminator" is separate from the Infrared camera, I assume though it shines IR light for the IR camera to see in the dark. But yea the picture looks like she is been blasted by a bright light not a great image and adds some confusion.

Think night vision goggles with an infrared light. In total pitch black environments with no light, infrared acts as a normal light when viewing through the night vision goggles. It's just not visible to the human eye.
