I don't think it actually changes the idle setpoint per se, but it holds the idle up. If you raise it, both cold and hot idle rise, and if you lower it, hot idle still aims for the target idle, while cold idle drops. Lower it too far and it will have a harder time hitting hot idle, and/or it may be easier to stall, because there's less ignition advance in reserve to control idle with.
