Yes, it's not a very obvious joke - at least, not to those who are not very familiar with the skating style of both Stephane and Evgeni. Those who know their styles very well (or, even, just Stephane's) can notice a spin, half bielmann spiral, some steps and small, a bit exaggerated hand jestures here and there that are not characteristic for Stephane, but are for Evgeni. But Stephane makes it all look so serious and natural, that less well-informed and/or attentive people most likely were not/won't be able to even notice that there's something funny in that performance
