However, if you put the system into DEFROST mode, it will run the A/C a bit to help clear the windows. This is very helpful... look at some of the older Japanese cars in the winter and you'll see the windows all fogged up!

Not correct. The AC compressor never runs if it is below 3C outside, and it should cut out if the evaporator falls below 5C. If you're using heat and the temperature is above 5C, the compressor will likely run a fair bit. But since the head pressure is so low at these temperatures, the compressor doesn't take much power from the engine.
If you want it off, you have to hit the "EC" button.
