No - it matches where the body is the last variable.  Not an empty body
- right?

With other words this case:

#+begin_src emacs-lisp
(byte-optimize-letX
 '(let ((a (+ 1 x))
        (b (+ 2 x))
        (c (+ 3 x)))
    c))

; ==> (progn (+ 1 x) (+ 2 x) (+ 3 x))

(byte-optimize-letX
 '(let* ((a (+ 1 x))
         (b (+ 2 a))
         (c (+ 3 b)))
    c))

;; ==> (let* ((a (+ 1 x)) (b (+ 2 a)))
;;       (+ 3 b))
#+end_src
