But the article suggests a higher responsibility: you should document your user's decision-making. You should tell them the context, the choices they have to make, and the consequences of their decisions.
I've worked on a "decision support system" with that responsibility and it got really messy, really fast. Humans love to argue about consequences, even 100% absolutely known ones. They also despise automated emails bearing uncertainty, as well as docs demanding binary choices when many more choices are available in reality.
I would hope the book beyond this article raises the concept of control. That is, to document a behavior, you need some guarantee (or enforcement) about that behavior so your documentation remains authoritative. IMO, the lack of authority/control is common, gaping blindspot of writing initiatives like https://www.plainlanguage.gov unfortunately.
