Why does the author of the 'Sai Leela' book pause the main narrative to tell the story of how he got the name 'Hemadpant'?

The author explains in Chapter 2 that he is fulfilling a promise made to the listeners in the previous chapter. He notes that at the end of every chapter, the words "Composed by the devotee Hemadpant" appear, which naturally raises curiosity about who "Pant" is. The author states that telling this sub-story is also an inspiration from Sai. He pauses the main life story of Sai to satisfy the reader's curiosity about his naming ceremony, believing that listening to this story will reveal its appropriateness before he continues with the sequence of Sai's life.
