Because even if it is the same soul, each Avatar is a unique individual, with their own experiences and personality, who has access to the memories, experiences and personalities of all the Avatars that went before.

Think of it as: the Avatar Spirit is passed on from one Avatar to the next, like a thread passing through individual beads and linking them all together into a single string that's connected into a whole.
