My understanding is that "first one whens" is intended for security. Global config is read first, and then local (per-user) configs are read later. Because the earlier config wins, the per-user configs can't override the global policy.
See, not so intuitive, and you would have known this by reading the documentation.

What I mean is that "first one wins" might be intuitive to you, but to me "last one wins" is, and apparently I was wrong, but I would have known at least, because I do read documentation.
It does make sense, indeed, that "first one wins", though.
