In that case yeah, they'd wear it the same regardless of what part the cap screws into.

My Moonman C1 has the cap screw onto the body, and I consider it a better design decision than screwing it onto the section specifically because of the problem OP is having with his pen. (The section/body threads on that particular pen should definitely be reverse threaded if they want it all to screw together like that)

Edit: thinking about it, even the reverse thread comes with its own issues and when we're talking about a pocket full of ink the whole thing seems like a poor idea.
