Repetition is useful for memory. If your aim is conversational, like this, it's unnecessary. But if you're telling a story, it's useful. Besides, the GP wants to reduce the literal repetition by replacing the identical words with synonyms. This is akin to writing in Inform 7 or similar interactive fiction systems. Or if, like me, you're terrible at coming up with character names, you can use <PROTAGONIST>, <ANTAGONIST>, etc. throughout while you're making outlines and such. GP would want to do something like that, with proper substitution of the name with other identifiers later on (full, partial, first, last, pronoun, nickname).
