Hmm... good point, doing it in completion-choices is not reliable, tho
using as completion table something like:

(lambda (string pred action)
  (let ((res (complete-with-action action completion-choices string pred)))
    (if (and (eq action nil)
             (assq (if (eq res t) string res) <expansion-alist>))
        (cdr (assq (if (eq res t) string res) <expansion-alist>))
      res)))

should work OK for prefix completion, but that means using the expansion
"by hand" rather than via expand-abbrev, which may not be an option.
