If you are referring to post #15 (only post on the thread that shows the piston) there is not even a ring installed on the piston, so not possible to comment on wear pattern of same.
Yup, that is what I see too.
By the way, thanks to Captn for posting the photos of the internals of the engine. Certainly interesting machine work on the crankcase. I don't see anything especially out of the ordinary about the cylinder though.
