Why did the author, Hemadpant, decide to interrupt the main narrative to explain the origin of his name?

The author felt it was necessary to pause and explain how he received the name "Hemadpant" for a couple of reasons, as mentioned in Chapter 2. He notes that he had already promised listeners at the end of the first chapter that he would tell this story. More importantly, he recognized that since every chapter of the "Sai Leela" book ends with the credit "Composed by the devotee Hemadpant," a doubt about who this person is would naturally arise in the reader's mind. He wanted to satisfy this curiosity, viewing the inclusion of this sub-story as an inspiration from Sai Baba himself.
