What specific promise did Sai Baba make to Dev about attending the feast, and how was it fulfilled?

When Dev invited Sai Baba to the Udyapan, Baba promised to attend. More specifically, as revealed later in the narrative from Chapter 40, He gave a clue about how He would arrive. Baba told Jog what he had told Dev: "'I will come only for the meal, bringing two others with me'." This promise was fulfilled perfectly, though not as Dev expected. Sai Baba, disguised as a Sanyasi, arrived at the feast with two other companions. All three were served and had their meal. Although Dev failed to recognize Him at the time, Baba later confirmed to Jog, "I said I would come with two others, and I went with two others," demonstrating that He meticulously keeps the letter of His word.
