Do you think that there's a point where we shouldn't bother to create a real world or an earth category? Let's say that there are 20 articles in the category Earth mammals and 19 of them would fit in the category Mammals from the real world. That's a difference of one and an overlap of 19...do we bother? Or there are 20 articles in the category Earth mammals and only 1 would fit in the category Mammals from the real world. That's an overlap of only one, but also a category with one page.
