What was the dynamic between Devidas, the Fakir, and Sai Baba as detailed in Chapter 5?

According to the account in Chapter 5, Devidas was a respected wise man in Shirdi whom Tatyaba and others regarded as a Guru. A scriptural debate was arranged between him and a visiting Fakir. Devidas's profound detachment led to his victory, causing the Fakir to leave for Vaijapur. Years later, the Fakir returned and humbly bowed to Sainath, his delusion of being a Guru having been dispelled. Throughout this, Sai Baba exemplified humility by treating Devidas as his own Guru, a stance he described as, "His Guruship to him, and my discipleship to me." This entire interaction, as narrated by Mahalsapati, is presented as Baba's profound play to teach a lesson on ego and discipleship.
