I didn't know that!
My observation of the left hand float is that it doesn't go high enough to register a full tank.

So I filled up to full tank today. I only managed to put 77.3l in and now I am a bit confused. Stopped straight after to VCDS the fuel level it shows 89l.
x + 4.5 + 77.3 = 89

If the fuel level sensors are to be trusted that means there were roughly 7 litres still in there when the range read zero and VCDS showed 0 litres.

Perhaps it is possible? Kind of reassuring, but also annoying, I assume I could have used at least another 3 of those litres without endangering the fuel pump?
Thats roughly another 15 miles!

I reckon, that on both my S8's there was usually about 2 gallons (9L) left in the tank when range was showing as zero.

That sounds about right. I find it so strange that so much fuel is left when range and fuel sensor reads zero. Unless its needed to save the fuel pump, but why so much?
