I believe those were the marketing blokes. "What do you nerdy types mean, '11' makes no sense? Just change the labelling on the panel! Problem solved! Next year we could even consider going to '12'."

@Stuart Castle - yes a great idea but watch the power budget. The PoE HAT is rated for up to 2.5A at 5V and the 7" Pi Touchscreen needs almost 500 mA alone. A 10" display likely more, mostly into the LED backlight. I bought the PoE HAT with a similar idea using the RPi 7" official touchscreen or a more sunlight-readable equivalent I found from NHD (ordered, still to be tested).
"There are probably industrial applications where PoE has advantages."... yes, a few, like the hundreds or thousands of WAP boxes on college or business campuses, where running power is a real PITA, so a huge gain for PoE. Not to mention mains power supplies are a common point of failure in such deployments: another win for PoE. At the endpoint (in this case the PoE HAT) you still need a switcher from the PoE 48V to the local 5 or 3.3V but that's way easier than a mains switcher. My PoE HAT is still in the box, curious to see if I'm bitten by this bug.
