With LAND 3 "a single fault cannot prevent the autopilot system from making an automatic landing (fail operational)"
With LAND 2 "a single fault cannot cause a significant deviation from the flight path (fail passive)"
We revert to 3a for LAND 2. Any further failure (below 200ft RA) will give NO AUTOLAND annunciation which requires an go-around unless adequate visual reference has been obtained.
Don't think any configuration problems could occur with LAND 2. Only a bit of nose up trim which is applied to assist in the flare.
