Up goes to the top and the horizontal ends up on whatever side it ends up on. I have a Russian scope that has the turret for horizontal on the "wrong" side but the reticle is a pillar style so it was kinda obvious which way was up even if I couldn't read Cyrilic (Russian writing?)
I get what you mean and while almost all scopes have the turret on the top and the right, not all do this so there are a few that stick out on the left.
