The act (in a text) of "pointing back" to some earlier part the same text is called "anaphoresis". (The reverse, that is pointing forward to what is to come, is more rare - it is called "cataphoresis").
Words like "his" - which implies a "he" who was already mentioned - or "there" - which implies an already mentioned place - perform anaphoresis ('anaphora' is the noun).
