Just for clarification:

Many where asking why the AT was doing the Autoland command sequence, while the AP was still tracking the glideslope and not going into FLARE (unannouced in FMA on a single channel approach)

We see here that AT was used in conjunction with AP/B on a single channel approach.

AP/B takes it's radar altitude from LRRA B, that worked fine.
AT takes RA only from LRRA A, regardless which Autopilot is enganged.
Even during a dual channel approach only LRRA 1 supplies data to the AT, that is because AT is a single channel system.

Anyhow... this was a major f**kup by the crew, sorry to say so...
