It's the English that I'm unhappy with.

"can go on OFF state" doesn't sound right.

It's a bit better, yes.  Although it's still a little difficult to
read.  In fact, I can't even recommend a suitable alternative, since I
still do not understand exactly what it is you're trying to say.

I guess there are too many '.*sleep.*' properties now, each with
slightly different syntax and meaning.  The situation is exacerbated
by one of the key examples is using the property with cells expected
i.e. non-bool.
