Your link indicates that I'm right. Scroll down to the 'examples of use page', and you see that adding up the 'SI (French style)' plus the second box below that yields by far the most countries.
"Most of the globe" does not obviously mean the same thing as "most countries". "Most of the people" would be a much more plausible interpretation than a metric that gives Swaziland equal weight with China.
"Most of the area" would also be a plausible interpretation, but "most countries" isn't.
Its actually the most plausible. If you go for 'most people', the most spoken language isn't English, its Chinese. Yet ask people, and they will happily point towards English. If you go for 'most area' you again run into a problem, because Russia and Canada are totally out of whack with regards to population per square km. 'Most countries' is the happy middle ground.
