Yeah, that passage is referring to Vlad's appearance in Fate/Apocrypha, where the Grail War is taking place in Trifas, Romania, just a few miles away from the town where he was born. That gives him a huge fame boost to his base stats due to all the local legends about him, and then his personal skill, Demonic Defender of the State, is also all about giving him the home field advantage. The Rider class is all about 'low stats, but multiple powerful Noble Phantasms', so the Lancer class was the best fit for the abilities they wanted him to have.
