Its 'pyramid structure', not inverted. It was used in newspapers for two reasons.
The first is because, yes it allows busy readers to access the most salient facts first. But secondly, and perhaps more importantly from the point of print newspaper production, it allowed subs to always cut from the bottom, without having to read the whole piece carefully...
Newspapers would go through several editions throughout the night as new stories came in or existing stories were expanded. What started life as a front page lead might find itself moved to page three and progressively shortened, possibly down to a 1 sentence news-in-brief NIB.
The pyramid style let subs always fit a story into the available space, simply by cutting everything progressively from the bottom.
This story in Wired is not a news story and is not written as a news story. It is a feature story and its construction follows different rules.
It's a very good feature story, in my opinion.
