Yep, it's the demand for cabin heat that is firing up the ICE. However, even though the ICE is running it's not moving the car as long as the battery is over about 18% charge. So your overall MPG will still be over 100, unless you are stopped a lot. Before Fall arrived, I could go days without the ICE even starting. But I won't have weather like that until next May most likely.
