Maybe he has seen it, maybe not, point is in EW number of counts are not infinte, so it's normal 2 persons sees the same count. It happened to me too though, an analyst posted same chart analyses as on my blog, coincidence or not,what matters is that another person validate your work by copying or having same approach to the chart. The goal is to predict probable price target, not to be 'first to see' :-) That's how I think at least.
But you are right to tell us you did it, and congrats that's a good analysis (as I can judge :-))
