Well when a DF user dies it is said that that DF will grow elsewhere. Also a DF is known to have a demon inside, so I think the black cloth served as a purpose of keeping the demon of the DF contained so he can absorb it. So no matter what he has 2 demons inside which is supposed to be impossible because you'll die. And using the information Marco provided about BB's irregular body shape, its possible he has 2 souls or more like a twin. It is said that a surviver of twins is as if he has 2 souls inside instead of 1. So it would make sense. The only thing that will contradict this is the possible idea that he could posses 3 DF, by the hints of having 2 skulls on the flag, 3 guns, 3 scars on Shanks, etc.
