No, I think it's exactly *not* confused on this point. There's a distinction between the idealised URI and the produced URI; in the produced URI, "%25" stands for "%" in the idealised URI.
We have no real choice but to use % since that was chosen years ago, and that means that the produced URI contains %25.
