Hello. You did not show the tragic elements identified by Aristoteles, nor did you show what Sophocles' work he analyzed was, which leaves your question very unspecified and does not allow me to give you an exact answer.
However, we can say that the allusion used by Sofocles in his works, together with other literary devices, improves the storyline and the audience's experience because it makes the story identifiable and real. Sofocles used these literary elements, to allow the public to see themselves in the plots and take that story as something that could happen in their lives. This made everything more exciting and impactful for people's lives and very identifiable.
