The article is about the software layout, not the physical layout as far as I can tell.

And people "typing non-English languages on a english keyboard" generally use a software layout native to their language on a physical english layout.

Wrt. Europe the differences between languages are sometimes not that big (EDIT: in their alphabet), so it's not uncommon to have some form of "internationalized layout" which contains all english letters + many common non English letters (e.g. äöüß for German and similar). Still it's called an international layout not a english layout with support for English dialects like German...
