I don't really agree with both of those replies, however I think I understand where Fantom and Intruder are coming from.
An approach to landing is just that. The approach finishes when touchdown occurs whatever the weather conditions.
During Cat3b conditions rollout guidance is given until the runway turnoff - so one could argue that you have full autoland protection up and until that point.
I agree with the sentiment of the replies in that the very difficult part is then taxiing to the stand.
