I think that's probably just another "unconventional" aspect of the Zeiss folding 35mm cameras and is a consequence of the advance and rewind knobs being on the bottom. I don't find it at all uncomfortable, and the knob wind is surprisingly quick and easy, especially as you get towards the end of the roll (more film on take up spool = larger diameter = greater length moved per turn). Take up spool on the right probably became standard with lever wind, having the advance lever on the right is probably easier for right handed people. Roll film cameras seem fairly arbitrary as to which side is feed and which is take up, with sometimes different format versions of the same model (e.g. 6x4.5 and 6x6) having them on opposite sides. I think I've heard of that one. What gets me is how some minilabs number the frames (and files from scans) in reverse order - they can't have thought everyone was using an EOS!
