Makes sense to me. It's very much along the lines of something that happens in class with my instructor. The art that we study is a traditional art. The techniques will all have very small variations depending on the person doing the attacking and the person doing the defending. Therefore, even though the techniques are "traditional" they must be up-dated for the individual. My instructor teaches the technique as it is traditionally done and then says "Now, make it your own." Very much "authentas".
