. . . the immigration officer actually tried to be helpful when he told you to visit on he day your Tourist Visa extensions runs out. The reason might be that if he issued the extension today, he would have needed to start the 60 days from today. He lets you apply for it on March 4th, so the 60 days will start on the March 4th. Thus he actually wants to ensure you receive the full amount of the 60 days Covid19 extension and don't lose any days until march 4th
