Is Step 22 from "learn accessibility by building a quizz" a joke?

Why? I didn’t add the placeholder on the previous step and the hint forced me to do it just to proceed to the next step of removing it… why would you do that? just say it on the previous step, no need to make the student add it just to remove it, or if it’s really necessary to explain it on two separate steps, just let students that didn’t add it on the previous step continue, and add the placeholder automatically and state that you added it anyways to teach best practices or whatever.
