I once knew that, it was recommended that for storage of batteries, i.e. leave them unplugged without any usage, it's a good thing to leave at 40% or so, to preserve life, maybe that setting is for that, and the 100% is for regular usage of charge/discharge.
I have no idea if that thing of 40% still holds true for newer batteries though, but maybe has something to do with that.
