Why did Jog lie to Bapusaheb Dev about Baba's whereabouts during the Udyapan ceremony?

The provided text does not support the claim that Jog lied to Bapusaheb Dev. On the contrary, Chapter 40 portrays Jog as a faithful and honest intermediary. When Dev wrote to Jog expressing his disappointment, Jog 'communicated the entire account at Sai's feet.' After Baba revealed that he had attended in disguise, Jog was filled with joy and promptly wrote a detailed letter back to Dev explaining the entire truth. It was this truthful account from Jog that cleared Dev's delusion and made him realize his mistake in failing to recognize Baba.
