No, I sense what he meant was that since all vampires are Akasha's progeny, it maybe what allows her to dominate them all (apart from age). I don't know if this is how it works with Anne, but I've sure read similar things in vampire mythology.
Add to that, we don't actually see fire flowing from her, its acts as possible evidence to support such a theory - maybe being the original, and all others having her blood allows her powers such as setting them alight (which wouldn't be pyrokinesis) - although it wouldn't hold in a debate like this without more proof.
I have not read the books, but I think I've read pyrokinesis is one of their powers, if that's true then it totally removes doubt she can control flames.
