You have to account for the actual mechanism at the top as the lever oscillation is much wider than the throw of the cam/wheel. It is not a mild ellipse at all.
If I had absolutely no idea what an elephant looked like, you would be correct. However, I have seen an elephant many times and if I could only see a leg, I wouldn't need to see anything else to know it was an elephant.

That being said, regarding the overall top mechanism, we don't really have much to go on with the exception of some very grainy film and some educated guesses.
