He may have nothing to do with the Island, and Ben is just lying to make it look like Widmore is in charge of something when he's not.
He is just a not-so-important Other, and will not have any major role in the next seasons (Evidence: Ben talked about him quite unconcerned. H would have cared more if it was someone very 'special', or some sort of Other leader.)
This footage was taped recently, because the tape was originally used to show Jack (on Nov 29th) the World Series footage.
He is one of the unimportant "footsoldier" Others that Ben recruited such as the ones he sent to the beach camp. Widmore wouldnt beat him if he was an original Other or someone otherwise important to the Island or the Others.
