Re: Cat III is not your normal ILS
"Nope, it cuts out at 50 feet and expects the pilot to keep final control during flare and rollout."
I'll see your 'Nope' and raise you another 'Nope'.
"At the appropriate height above the ground (as indicated by the radio altimeter) the flight control computer will retard the throttles and initiate a pitch-up maneuver [sic]. The purpose of this "flare" is to reduce the energy of the aircraft such that it "stops flying" and settles onto the runway."
From Wikipedia - https://en.wikipedia.org/wiki/Autoland
(Yeah, I know it's Wikipedia, but it has quite a reasonable explanation.)
Also: "The lateral guidance from the ILS localiser would however be usable right to the end of the landing roll, and hence is used to feed the rudder channel of the autopilot after touchdown."
At no point does it say anything about pilot interaction being required for the flare or for maintaining the centreline during rollout.
There are different versions of 'autoland' which may be confusing some folk. What we are talking about here is Cat IIIC.
