I think you are agreeing with the parent comment with a tone of disagreement.
They say they let cold air in during the winter because they want to lower the humidity.
Then you say that, if you let cold air in (and then let it heat back up again) then you end up with lower humidity.
The only thing you might disagree on is exactly what humidity you would like inside your house. But that's subjective. (As it happens, I agree with them: I often find it too humid inside during the winter, because I've restricted airflow to keep the heat in.)
