`org-element-context' never returns contents of objects or elements.

You could do the following

  (let ((citation (org-element-lineage (org-element-context) '(citation) t))
        references)
    (save-excursion
      (goto-char (org-element-property :contents-begin citation))
      (let ((end (org-element-property :contents-end citation)))
        (while (< (point) end)
          (let ((reference (org-element-lineage
                            (org-element-context) '(citation-reference) t))))
          (push reference references)
          (goto-char (org-element-property :end reference)))))
    (nreverse references))
