To be honest, I think it does.
At first, I thought Kun was guilty and had simply tried to twat Reid and missed slightly. I was "OK" with him being banned because I thought fair enough, he deserves it. But looking at it from this angle puts a completely different complexion on it for me. It looks to me like Kun was about to jump for the ball, gets a hand in his face, and therefore ducks out of the way. His arm is raised partly because he was about to jump and partly to keep Reid away. It doesn't look like a deliberate elbow at all.
And even more compelling for me is that had Kun wanted to elbow Reid, he would have elbowed him!
