The thing is that Hussie deliberately ripped off Doc Scratch's/Lord English's leg whilst shaking him violently.
So this wouldn't be relevant at all if Hussie wouldn't have interfered with the Intermission.
Or maybe Doc Scratch's death in any universe includes the detachment of his leg. He's made it pretty clear that his role in any universe is pretty much the same. Maybe specifics like that No wait that's stupid. We're already aware that English's appearance is based on Scratch in some way, such as appearing similar to Cal.
Also, how did Scratch technically die? Did Hussie actually kill him?
