Unless you have seen more pictures than me, I'm not sure you can be any more sure of that than about an engine failure...
Until we get more information (which could be a while) we can't even rule-out the possibility he was carrying a starboard engine failure for a while, had trimmed the rudder port to compensate, and only when he reduced power to land did this cause control difficulties.
