Just hit the power button 5 times on my iPhone 13 Pro, and it locked down FaceID as I'd expect (while bringing up the Reset/Power Off screen). You've described an alternative method, not the only.
Which OS are you updated to (no please don't post it)? not 15.1.x? Have you disabled wallet, Siri, and SOS?
It doesn't work on any of the 5x 12s and 13s (pro and not) I just tried. It did work on an 11, which was not updated to 15.
You also risk the accidental activation of an SOS call.
I think you need to turn on the power button clicking 5 times feature by turning on the "Call with Side Button" option in Settings under Emergency SOS. I'd also suggest turning off Auto Call if you want to use it like this.
Yes this is kinda buried and not clear at all that this function also disables FaceID but it does.
