In jay z song do you think he was talking about beanine sigel in this part?

the dig a hole song i think was directed at cam'ron. cams come home with me album went platinum while on rocafella. camron had a roc chain too. and throwing the roc sign up outside the coup was referring to cam getting carjacked and shot. cam said he seen a guy throw up a roc sign outside his lambo before he got shot. the other joe budden part not sure
