Results are different between your link and https://twitter.com/search?q=Giorgia%20Meloni&src=typed_quer... (i.e. the "videos" tab, and a normal search with "filter:videos" appended)

The article is referring to the former (as can be seen from the screenshot).

And the results seem to be changing - when before I got zero results for the video tab search, I now get exactly one - a video posted 3 hours ago.
