How? It would load the HTML just as often and not download it a second time as that would invalidate the usage

True for users who hover over links they decide not to visit

I'm guessing you didn't read the linked article? It preloads after 65ms on hover, at which point it estimates a 50% chance that the user will click. Hence "loaded twice as much".

Yes, that's the point.
