Why was Chapter 53 of the Shri Sai Satcharitra not written by the original author, Hemadpant?

Chapter 53 explains that the original author, Hemadpant, was unable to complete the book as he had intended. He had made a promise in the previous chapter to provide a summary, but as the text states, he "suddenly passed away, leaving everyone’s heart grieved." This unexpected event left the work unfinished. The chapter notes that while the general rule is for the original author to complete a book, this was an exception where "Baba’s will is more powerful" than human plans. Hemadpant's son, Shri Gajanan, later provided his father's vast records to the new author to help complete the task, as described in Chapter 53.
