JT didn't forget people abroad, he told them to come back now not on April 15th.
You misunderstood him. He's been in India for months, since before the COVID-19 crisis and his return ticket was booked for April 15th. He didn't just buy the ticket now. It was bought last year.
He's trying to get back now (well, two weeks ago) when the borders started closing, and not April 15th.
