You're welcome.  I've never used biblatex, but the way I get it the
syntax for §3.8.3 Qualified Citation Lists is like this:

\parencites(multiprenote)(multipostnote)
           [prenote][postnote]{key_1}
           [prenote][postnote]{key_2}
           ...
           [prenote][postnote]{key_n}

I don't understand why `LaTeX-arg-biblatex-cites' has this:

  (let ((items t) (noinsert nil))
    (while items
      ...
      (setq items (TeX-completing-read-multiple
                   (TeX-argument-prompt optional prompt "Key")
                   (LaTeX-bibitem-list)))

If only one key is needed, why `TeX-completing-read-multiple'?  I think
you can have it all by doing something like:

    (setq items (if (and (fboundp 'reftex-citation)
                         (fboundp 'reftex-plug-flag)
                         (reftex-plug-flag 3))
                    (reftex-citation t)
                  (completing-read
                   (TeX-argument-prompt optional prompt "Key")
                   (LaTeX-bibitem-list))))

And further down:

    (TeX-argument-insert items optional)

Or am I missing something?

That is somewhat hidden in the manual:  Try `='.

7. Commands[1]

Command: reftex-citation
         ...
         While entering the regexp, completion on knows citation keys is
         possible. ‘=’ is a good regular expression to match all entries
         in all files.
