I think that Chris' goals on this part is to have the game itself teach players, instead of using the tutorial, in order to make the tutorial as simple as possible. So basically if it could NOT be in the tutorial in the first place, but people understood it anyway, he'd be happier as far as I can tell.
I'm writing this because I think it failed on this part - however, the only thing I'd be looking for here is descriptions to make the existing tooltips clearer, or a suggestion to have the link between both being more intuitive.
