You are correct! This is known as signaling. If you hate the article, don’t understand it or would prefer to close the tab, then you have recognized that the signal was not for you. This is excellent. The author has written something that did not waste your time and has limited the people who interact with him to those who want to receive the signal. Be happy that he sent the signal early on. This is a sign of his respect for your time.

It would be confusing to call that signaling because signaling already means something different.
