No, the last paragraph says that these results (seen on a desktop PC) suggest that if you're on lower powered hardware (like a handheld) you may want to ditch the preinstalled Windows and try a Linux install to get a bit more performance.
Which is very debatable on a couple of counts, including the worse 1% lows, the fact that these desktop GPU results may or may not carry over to low TDP AMD APUs and that there's no guarantee that you'll get support for other custom features like the Legion Go's funky detachable controllers. But that's what it's saying, not that the results are about handheld performance.
As for the other thing, man, you're all over this thread being weirdly hostile, All I'm saying is you don't have to be. This isn't a big deal, the article isn't clickbait and nobody is out to get you. There are actually enough things here that are interesting to debate without trying to make this about some weird journalism standards thing. Some of them are even about how shaky some of the reporting is, if that's your angle. It's just... not for the reasons you're getting all worked up about.
