We actually do have very slightly binocular smell. Enough that if you close your eyes and have someone hold something scented on on side of your face you can tell better than chance where it’s coming from. It works because at any given time one of our nostrils is open while the other is nearly closed. These actually cycle over time, you’ve probably noticed it before. The purpose of the restricted nostril is to give more time for the smell receptors as you breath in. The side effect is that there is a slight difference in smell strength between each nostril, just enough for directional info!
