Google Definition: Reincarnation: The rebirth of a soul in a new body.

Let's take Inuyasha for example. After Kikyo the priestess dies in the feudal age of Japan, she is reincarnated in Kagome, an ordinary Japanese high school girl. They both have the same soul. Same thing with Avatar, which also has the two souls dynamic.
