No, in my case they do relate with brightness.

This works different in my system. If I reduce the brightness by half with F-
keys, actual_brighness changes from 1388 to 763. If I go back to maximum 
brightness, and then echo 763 to brightness, the screen brightness is indeed 
half, as expected.

This is what happens with the standard KDE's power management funtionality. 
After some time the system is inactive, the screen is turned off.
