I don't think he means to imply that there are "fake" Germans. I think he means "actual" Germans as in the Germanic-speaking peoples of central Europe excluding the Dutch-- Germans in Germany proper, or what ultimately became Germany proper plus Austria (in terms of EU IV's timeline, though actual unification under Prussia is outside of EU IV's timeline). Roughly the people who ended up speaking modern German vs. those who speak Dutch languages, which differed more from local High German dialects than those individual dialects did from each other, from my understanding. Basically, two sub-categories of "Germanic peoples," differentiated due to major cultural and linguistic differences. I'm sure there are people who understand this in far greater detail than I do, however.
