You are kidding right? Supposed to happen since when? First of all, after wobbling Caroline always takes off from the wrong edge on her LUTZ that is why she always gets the edge call for that jump. She basically doesn't do it correctly.
And yes, there are quite many who do not wobble and take off from the correct edge. To check out a correct one, rewatch Rochette's LP. It is true it took her a few years to fix it, but she succeeded to have a very good one.
And before there wee many who had a good outside edge. (See Slutskaya, Arakawa for example).
Reality is, this rule was not applied strictly before 2007. Under today's rules, Sarah Hughes or Tara Lipinski would have not been olympic champions with those routines, both of them were clear flutzers
