You understood correctly and I appreciate your feedback very much.
I have, since posting above, investigated a bit more and arrived to similar conclusions to yours. I thought that color coding connections and cables, along with careful case design would be enough but, as you put it, it is too vulnerable to mistakes. I also had trouble finding a cable that would feature female connections on both ends so it was prone to be redesigned anyway.
Do you know any type of cabling standard that would be adequate for connecting the powersupply module and the eurorack module case?
