The -P option works as documented, and it's behaviour is reasonable.
It is intended for use with archives created by other, non-POSIX, ar
programs.

My recommendation was to extend the -P option to work when creating an
archive as well.

I'm fairly certain that there is nothing else you can do to
succesfully store and modify different files in the same archive with
the same basename and different full pathnames.
