When you have liquid coffee, what you really have is a bunch of little pieces of solid coffee sitting in the liquid water. You cant feel the solid parts because theyre really really small and mixed in really really good. When you heat it up, only the water leaves through the steam, the solid coffee cant go up with it. So when the steam becomes liquid again its just water. You can do this with water you find that may not be safe to drink, since the same process also gets rid of things like sand or dirt that you dont want to drink.
