The article is very good but you have to consider the existence of other filters, not only the Bayer one.
And the Canon Dual Pixel AF that works a bit different than the article explains https://www.canonwatch.com/dual-pixel-af-has-become-a-canon-... (but the substance is the same)
In the article it is clearly acknowledged that there are different types. When you create a introduction like this you kind of have to limit your scope
