It was buried way deep in the article, but:

> But what exactly is this trajectory? One thing is clear: It’s not like a classical trajectory, meaning a path taken in space. It’s more like the path taken through the abstract space of possible states the system might have, which is called Hilbert space.

QTT is not a definite prediction of classical physical trajectory.

Although classical physical trajectory is one if the possible states QTT helps us predict. It’s more than that, not less.
