I don't think it happened imediately after the war, Marco probably tried to keep WB's old territory from BB, then when BB became a proper Yonkou, Marco would have been in a seriously difficult situation with an emperor and the marines crazed dog of a FA hunting him, and would have had to choose one to side with. Sakazuki is the lesser of two evils and is controlled by the expectations of his subordinates and those of the public, Kong and the Gorosei so I think Marco and co. would be safe as Shichibukai, and it would give them a safe platform from which to plot against BB.
