So is the story “only tracing the path” where nearly all past time-turner use happens to have gone down the “good” branch?
On a charitable interpretation: every story ever written (excluding directly self-contradictory ones) describes a universe (quantum branch) which exists. Choice of story to write == choice of universe evolution to describe. Shminux just told you what evolution is described by HP stories. It’s about as valid as saying “here’s a story where magic works, although it never does in our own universe, and the reason is—there’s such a universe out there and we just chose to tell its story”.
Does that actually explain anything more than saying “it’s magic, and here are its laws” would? Probably not. But it’s still a perfectly valid statement to make.

As I mentioned in the other comment, except for the actual appearance of a person from nowhere in the branched timeline, no laws of physics are broken.
