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,

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))
