I think you have mistaken "normalization rules" in this context with Unicode normalization algorithms. I'm specifically talking about documents like [1], which are essentially more detailed and concrete versions of the original Han-unification rules. (Note that normalization rules themselves are distinct from the eventual unification. It takes further works to actually decide whether the unification is possible or not.)
