What's happening is the cold air sinking down that flue. You may or may not be getting smoke down it from the other one. I used to get a smoky smell down mine even though I didn't have the other one burning. I found that my furnace's forced draft direct vent was creating a negative pressure in the house and the easiest place for the outside air to equalize was through the chimney. The forced draft system has been tossed.
