If I was a fingerprinting company, I'd be cross-referencing signals between browsers for sure.

If the browser header says windows but the fonts available says linux, that's a very distinctive signal.

And if the UA says Chrome but some other signal says not-chrome, that's very distinctive as well.

The article also mentions this, and suggests the UA is not a silver bullet. That said, they didn’t go into specifics. I’m assuming there are other details that correlate to particular browsers that will betray a false UA. Plus, having a UA that says Chrome while including an extension that’s exclusive to Safari (tor example) will not only contradict the UA, but it will also be a highly distinctive datapoint for fingerprinting, in and of itself.
