I agree that is annoying, but according to this comment in do-auto-fill
it is intentional:

			       ;; If this is after period and a single space,
			       ;; move back once more--we don't want to break
			       ;; the line there and make it look like a
			       ;; sentence end.

You can work around it by setting sentence-end-double-space to nil
when auto-filling:

(defadvice do-auto-fill (around sentence-end-double-space activate)
   "Temporarily bind `sentence-end-double-space' to nil, to allow line breaks
after abbreviations etc."
   (let ((sentence-end-double-space nil))
     ad-do-it))
