If you don't hold the inflater properly (vertically), you will get liquid CO2 in the nozzle which will probably freeze into a solid and prevent any more CO2 from going into your tire.
Actually, I think what you are experiencing when a valve freezes up is ice formed from water vapor in the air. While some liquid CO2 might shoot out of an inflator, it quickly turns to gas under atmospheric pressure.
