Why wasn't the Shri Sai Satcharitra originally completed by Hemadpant?

According to Chapter 53 of the Shri Sai Satcharitra, the original author, Hemadpant, was unable to complete the book because he passed away suddenly. In a previous chapter, he had made a promise to provide a summary to conclude the work, but this did not happen. The text notes that his sudden passing left everyone grieved and uncertain about how to proceed with the promised summary. His son, Shri Gajanan, later made his father's extensive records available to the person who would eventually complete the book, ensuring Hemadpant's work could be finished.
