Pupils accommodate. Focusing on something far will make your pupil get larger and focusing on something near will make it get smaller.
Basically every normal person’s pupil does this. My guess is that person in the article is actually just changing focus without really thinking about it. Given that changing focus activates muscles in the eyes, you might be convinced that you are actively controlling the muscles in the eyes directly, and not through changing focus. In addition, the “finding” of this article is based entirely on the persons subjective experience.
Thus I think the professor found someone who accomodates as normal, but has a subjective sensation of controlling his pupils when he changes his focus.
