They did? I did not know that. I knew that Xseed took more liberties when localizing the games (which I liked). But I thought that the script was liked well enough by the community that they'd just stick with it.
To be honest, as far as I can remember, there were a couple of threads on 4chan comparing the Xseed script with the original Japanese one and I found the Japanese one to be a bit bland. But maybe there was a bias in what was picked as examples in those threads.
