I read that Amuso got paranoid in jail and felt that Casso got him picked up so he could take the top spot on the street. Apparently when all this talk of a big escape was going on Amuso just said stuff it and clipped his wings. Also he couldn’t clip him whilst cassO was on the street as Casso had more power than him. When they was both inside it was a level playing field and all that was left were the official stripes.
