Really?  Does `C-c [' run the very same function?

,----[ C-h k C-c [ ]
| C-c [ runs the command reftex-citation, which is an interactive autoloaded
| compiled Lisp function in `reftex-cite.el'.
| 
| It is bound to C-c [, <menu-bar> <Ref> <\cite>.
| 
| (reftex-citation &optional NO-INSERT FORMAT-KEY)
| 
| Make a citation using BibTeX database files.
| After prompting for a regular expression, scans the buffers with
| bibtex entries (taken from the \bibliography command) and offers the
| matching entries for selection.  The selected entry is formatted according
| to `reftex-cite-format' and inserted into the buffer.
| 
| If NO-INSERT is non-nil, nothing is inserted, only the selected key returned.
| 
| FORMAT-KEY can be used to pre-select a citation format.
| 
| When called with a `C-u' prefix, prompt for optional arguments in
| cite macros.  When called with a numeric prefix, make that many
| citations.  When called with point inside the braces of a `\cite'
| command, it will add another key, ignoring the value of
| `reftex-cite-format'.
| 
| The regular expression uses an expanded syntax: && is interpreted as `and'.
| Thus, `aaaa&&bbb' matches entries which contain both `aaaa' and `bbb'.
| While entering the regexp, completion on knows citation keys is possible.
| `=' is a good regular expression to match all entries in all files.

And does regex search work in addition to completion?

Maybe the difference is that you use the biber patches?
