"What I care about is being able to click into my skis for the rest of my life. I care about being on top of the mountains with my best friends. If I'm on my skis, I've got a big smile on my face. And I want to keep it that way." T-Hall http://vimeo.com/thenewsolution
then your opinion is wrong. The point of a butter is to have pressure on the ski the whole time. What you described is just doing a 180 landing on your nose, flexing and poping another 180. Like you described.
