Keterys, that's my fault; using imprecise language. You are correct and that's the way we've been using it (for the most part--those first few levels I was not paying enough attention to the wizard's castings). In the first case (with the stirges, because they were flying) the wizard centered it on her location. In the other case with the zombies I believe it was slightly off-center (as per a more usual cast).
