i had the same 'why's it doing that' thoughts originally too. but as mentioned previously, it is on for a reason, and it does shut off if conditions warrant it. mine has shut off, and come back on later if the moisture content in the cabin increases.
something to try, if i remember correctly, when you are trying to turn the a/c off in auto mode, i think if the air is in the recirculating mode it won't turn off because you can't use recirc. with anything other than a/c. if you switch the air flow to outside air you can turn the a/c off. [i think]
of course the air compressor will always be on in defrost mode.

A/c does not operate below 35-40 f
Following is from the Owner's Manual, as I said before I think the set point for the A/C not to operate is about 38 F outside temperature:
"The air conditioning
does not operate at temperatures below approximately
35°F to 40°F (2°C to 4°C). If the system is operating in
the AUTO mode, turning the air conditioning off will
delete AUTO from the digital display and show current
mode and fan settings. The AUTO button must be
pressed to return to the automatic mode operation."
This is a protection to prevent the A/C from freezing, plus defrosting (or should I say dehumidifying) isn't really needed when outside temperature approaches the freezing point.

Thanks for the replies all.
This morning, it was from 17-20 degrees F and as I had the system on AUTO and the temp set from 75-82 F, the A/C light was NOT ON.
I'll now be using AUTO this winter, nice. I thought something in my controller was not working.
