What was Jog's role in the story of Dev's Udyapan ceremony and Sai Baba's disguised appearance?

In the account of Dev's Udyapan ceremony from Chapter 40, Jog served as a crucial intermediary between the devotee Dev and Sai Baba. After Dev felt disappointed by Baba's apparent absence, he wrote a letter to Jog expressing his confusion and feeling of being deceived. Jog then "communicated the entire account at Sai's feet." In response, Baba revealed the truth of how he had attended in disguise. Subsequently, Jog relayed Baba's full explanation back to Dev in a detailed letter, which ultimately led to Dev's profound realization and remorse.
