I'm not the Grandmaster when it comes to reading ancient Greek, but notice this: "epi de Dorou tou Hellenos ten hupo ten Ossa te kai ton Olumpon choren, kaleomenen de Histiaiotin: ek de tes Histiaiotidos hos exanetsto hupo Kadmeionoikee en PindoiMakednon kaleomenon"-it looks to me that in both instances, he is indicating what the region is called, not the people. So it should be translated as the Perseus version indeed translates it. The region of Pindus was known as Macedonia, not that the Dorians were here known as Macedonians.
