C'mon - it's only 1 degree. Probably a rounding error each way. There are many airports around the world where autoland is permitted with a 1 degree difference between QDM & LOC heading.
Haven't seen any autoland runways with greater than 1 degree though.
Interestingly, the wording in my 744 FCTM is slightly different and says
"Autoland should not be attempted unless the final approach course path is aligned with the runway centreline. If the localiser beam is offset from the centreline the AFDS ROLLOUT mode may cause the aircraft to depart the runway."
Also - not sure about the 737, but should you be flying to Cat II minima with a single autpilot engaged? Might be a 737 thing, but in my experience on 767 and 744 you would have at least 2 autopilots engaged for Cat II minima.
