The airco air is dehumidified by the temp. drop. That's why many high end compressed air systems use a refrigerant dehumidifier as well as a dessicant (medical/dental systems come to mind). This dehumidified air defrosts by "drying" the glass because of it's lower relative humidity. Hot air works by raising the "dew point" of the glass above the temp. that moisture will condense, relative to it's % humidity. It makes sense if you say it really fast.
