Yes its normal, and your thinking isn't screwed up.
Sometimes, but not always, there are markings on the nuts or the studs. Nuts will have a different color or line on them. Studs may have an L stamped on the head. One set of Crager closed nuts I have uses a different size hex for the lefties. They are easy to work with. All you have to do is run your clock backwards.
