On some cameras doing a manual cleaning (or two in succession) also causes the firmware to detect and map out "hot" pixels.
So yes, it does make sense to mention.

This not stated in the manual. And if true, what happens when some is physically cleaning the sensor? The sensor will be exposed to all kinds of lights and colors. How will it know which pixels to remap?

It's a well-known "secret" "back door".
This has nothing to do with physically cleaning. Only asking the camera to self-clean.
