OK, you clearly did not read the article because you are incorrect.

That statement you quote is referring to the still image in the article, below the video, which is of an entirely different star and system of planets (Fomahault b).

The video has a time legend /embedded in the movie/, at the bottom of the frame clearly showing when the observation for each frame of the video was taken.

NASA was being plenty up front here, I think you maybe just skimmed the article slightly too quickly.
