I'm not sure I understand how this precludes the wonder they had about how it knew how to do it, whether it was today or a week ago xD

To be clear if you read the article they mention that the clouds were being reported for years and it was only in 2017 that they categorized them and established an explanation for them.

It took 9 years for the classification to be accepted by the World Meteorological Organization

It isn't. This made some rounds on reddit a few weeks ago and other angles of the same clouds were shown, it's not fake.
