Nice way to say, "we dumbed it down and removed useful features."
It's about being able to ship new features when they are ready, instead of waiting for a 'major' new version.
This release cycle makes the most sense for 'evergreen' software like a web browser. There's a reason why every major browser has adopted it.
The only version that matters for a web browser is the 'latest' version.
Firefox has been steadily closing the version number gap over the past few years. Today, there's Firefox 100 next to Chrome 101. Firefox will probably lap them sometime this year. Firefox 105 planned release on August 23rd, but Chromium 105 on August 30th.

Both are on a 4 week release cycle now so it's up to any delays to change the gap.
