If the "carpet" is not seen at minimums, then the missed approach is executed, with the autopilot still engaged.

On the 757 if during an autoland approach, following LAND 3 annunciation, the Autoland Status Indicator (ASA) changes to LAND 2, execute a manual landing (weather permitting), or execute a manual go-around.
So it could be totally normal to do a manual go-around during a CAT 3 just an example, there are other scenarios which could make you do a manual go-around. What are saying, you should never disconnect during an autoland?
