Yes, low idle leaves a lot unburnt fuel traveling though the system (the flame in the combustion chamber takes a drastically different and far smaller shape at idle). So higher idle reforms the flame into a ball shape (which burns far more effectively) and burns off nearly all of the fuel. So low idle is creating a wet system and high-idle + is dry, and you want a dry system. <--- layman terms.
