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 I think Marco and co. would be safe as Shichibukai, and it would give them a safe platform from which to plot against BB.
