I'm pretty sure that the winter driving scenario you observed wasn't because it was letting outside air in. Rather, it was doing exactly what I described above, namely heating the rest of the cabin but blowing cool air through the front vents since you had it on the Cold side.
I've talked to a few of my colleagues and that is what they told me. I just leave mine on the Blue regardless lol. Maybe I'll shoot corporate an email seeing if they can get me a 100% correct answer
