I guess, the idea is that you cannot target both America1 and America3 with the same product. Take into account that America3 doesn't have a lot of disposable income in the first place, and going after a similar target audience in another country becomes a much more sensible choice than trying to expand into a different audience in your own.

> What's a reason that wouldn't also apply to india2,3?

If I understand correctly, it would also apply to India2-3, that's why nobody's proposing that.
