Since the Rwy 36C-Loc did not provide rollout guidance (note #4 on approach plate), that ILS-Loc could NOT be used for a Cat-3 Autoland
I have been thinking the same as you, sleeper, - Cat 3 Autoland and Cat 3 Autoland with rollout are
separate things. It is perfectly possible to do a Cat 3 Autoland (or Cat 2 Autoland) and disconnect the autopilot after nosewheel touchdown!
