* Docstring prevents constant from being fully byte-compiled

Byte-compile the following (Emacs 23.3.1)
(defconst A "A")
(defconst B "B")
(defconst AB1
(concat constA constB))
(defconst AB2
(concat constA constB)
"docstring")
I get
(byte-code "\303\bB\x10\304\305!\210\306\bB\x10\307\310!\210\311\bB\x10\312 \nP!\207" [current-load-list constA constB A (lambda (#1=#:defconst-tmp-var) (defconst A #1#)) "A" B (lambda (#2=#:defconst-tmp-var) (defconst B #2#)) "B" AB1 (lambda (#3=#:defconst-tmp-var) (defconst AB1 #3#))] 3)
#@11 docstring\x1f
(defconst AB2 (concat constA constB) (#$ . 800))
Note that AB2 retains the original (non-byte-compiled) definition, while AB1 does not.
Is that actually the case? Is AB2 byte-compiled, or not?
Why does the presence of the docstring make a difference?
