matching up notches when adjusting chain

Okay, maybe a stupid question, but I'll ask it anyway. You know how you are supposed to match up the notches on the swing arm when adjusting the chain? There is a longer notch that I assume is to help you see and therefore count them (for visual reference).

The thing is, that longer notch is about four or five over from the left when looking at the bike with the front tire to your left, but about four or five over from the right when looking at the bike with the front tire on your right. So, ideally, do I try match those up? Or would you count four from the left on each side (or four from the right on each side, or whatever)?

I hope I asked that clearly enough,
