The way I see it this is by design.  Looking at the function
`reftex-extract-bib-entries-from-thebibliography' which does this part
of the work (invoked from `reftex-offer-bib-menu'), there is a comment
saying[1]:

;; Read a regexp, completing on known citation keys.

So you can choose one exact key but you're still "warped" to the
citation menu.  I suspect the reason is that you can do more stuff in
that buffer and not only saying "please insert this key".

If one wants to insert citation keys without the RefTeX procedure, I
suggest to use other complementary solutions like `TeX-complete-symbol'
(provided by AUCTeX) or possibly company-reftex-citations (provided by
company-reftex[2]).

Best, Arash
