You just asked the pertinent question. Of course it does. It simply reduces the radius of spread from the wearers respiratory areas out into the surrounding environment. Some masks accomplish this better than other masks but they all help somewhat. This is why you cover your mouth when you sneeze etc.. Not perfection, just decreased spread.
