While this is indeed how the slider is supposed to work, the problem here is the screen will dim to that set level after about a minute of idle (or sometimes even if there is no idling), regardless of whether "dim screen while idle" is set or whether the user has set a screen brightness other than that setting manually.
"Dim when idle" should only do so when the option is selected.
