Well as someone whose job this is I can tell you it is not a bad landing, not good but not bad. The runway is HUGE, maybe he lost some speed in the flare due to wind shifting so left the thrust on to avoid a hard landing, maybe he was carrying extra speed due to the conditions and floated a bit, maybe there was a gust in the flare that caused a float, maybe he just flared a bit too much and floated, why are you continuing to try to justify this as a terrible landing? It is not.

It is not sop in any airline to take over only when it says retard. That is what you would do if conducting an autoland with the trust levers but it does not indicate the point to disconnect the autopilot. Usually pilots hand fly it for some or all of the approach. There is nothing in our sops thats says you cannot hand fly it from top of descent. The wording which I expect is similar to most airlines is along the lines of to use an appropriate level of automation for the prevailing situation.
