Hello. You did not enter the text to which this question refers, which makes it very difficult to answer it exactly. However, I will try to help you in the best possible way.
As you showed that the word "author" in line 10 was used as a proper noun, we can consider that the same word in line 4 was used in a general way and did not specify an exact person.
