Why can't `(La)TeX-mode' return the correct result:

(delq nil (mapcar (lambda (buf)
                    (with-current-buffer buf
                      (when (eq major-mode 'TeX-mode)
                        (cons (buffer-file-name buf)
                              (TeX-master-file "pdf")))))
                  (buffer-list)))
nil

(delq nil (mapcar (lambda (buf)
                    (with-current-buffer buf
                      (when (eq major-mode 'LaTeX-mode)
                        (cons (buffer-file-name buf)
                              (TeX-master-file "pdf")))))
                  (buffer-list)))
nil
