It's interesting, yeah, but kind of makes sense. Eisen switched away from the Dracheneisen character hook and into full Vanhelsing.exe, and got a new trickbag with it. Meanwhile, in 1st ed, Castillian magic was, in flavor, almost extinct due to the Rilasciare and its restriction to royal blood. Which of course, due to the Benevolent Drow principle, meant every other party had a Castillian sorcerer, but still in flavor it makes sense.
