I read some comments on a Stephane fan forum that predicted this would happen. The poster said that Mishin has a habit of seeking out "name" choreographers to impress the judges and then waters down the programs to the point where they no longer resemble the original. There may be a grain of truth in that, or it could be that he is just really stuck in his ways. He knows what will be enough for his skater to win, so why make the choreo any more complicated than necessary (this isn't my opinion necessarily, but I think that's how he sees it).
We have no way of seeing the original program, and we don't know what the end result will look like at all, so I don't think there is any reason to get hung up on what he says here. Stephane knows Mishin for many years, & if they didn't respect each other I doubt they would be leading skate camps together, or that Stephane would have gone to Russia to pay his respects at Mishin's jubilee, etc. And Mishin says a lot of things that aren't to be taken too literally.
