Possibly something missing here in the translation. FOs may land the aircraft in Cat I conditions. The Ops Manual used to say, (and probably still does), that in visibility of 2000m or less an autoland is

If company policy on the B777 doesn't allow FOs to carry out
practice autolands in Cat I conditions then
maybe the captain was using this one to maintain his currency. All a bit irrelevant now!
