hmm not really. It's more pointing out a good reason for the global disparity. It's a simple statistical thought process... another example is that the US is also heavily overrepresented in the number of LGBT people, because many other countries, particularly high-population countries repress that.
If you don't compare all-else being equal, you're going to have other factors playing into the resulting figure.
