Grammar Question and Answer: Toni Morrison's genius enables her to ...

After reading a page in Oxford Seminars, an ESL course, I was confused about the "mistake" in the following sentence:

the answer boils down to this explanation:

"Modern linguists prefer to work using concepts such as discourse analysis, in which the topic is clearly Toni Morrison, and it is legitimate for a pronoun to refer back to this implied topic.
