Why wasn't the summary of the Shri Sai Satcharitra written by the original author, Hemadpant?

According to Chapter 53 of the Shri Sai Satcharitra, the original author, Panta Hemad (Dabholkar), had promised to review the book and provide a summary to complete it. However, this did not happen because he suddenly passed away, leaving his work unfinished. The text explicitly states, "Hemad suddenly passed away, leaving everyone’s heart grieved." After his death, his son, Shri Gajanan, went through his vast records but could not find the promised summary among the notes, which were written on scraps of paper. This unfortunate event necessitated another author to take up the task of writing the concluding summary, as detailed in Chapter 53.
