That's the way the anime was released and it's the recommended order if you watch the anime (and don't read the LN). The LN order is a bit different, but the anime is adapted in a way that makes the broadcast order the intended watch order.
It's actually rather simple, but for some reason, people love to act like it's super complicated. Not helped by some making idiotically huge charts that are completely unnecessary and serve no purpose except to turn people off Monogatari.
Do not watch it in chronological order (unless it's a rewatch). It's one of those works that you're not supposed to watch like that, something that, for some reason, is hard to grasp for some people, despite being far from unique. And really, Monogatari is not as confusing as some make it out to be, so there's really no need to watch it like that.
