Announcement at Seawoods station not making sense

It's quite cold in Navi Mumbai today and a weird announcement hit our almost numb ears at Seawoods station in the morning. The announcer said something like - After the Belapur-CST train, a special train has left from Vashi to CST.

Whatever it meant, I presume it makes the trains less crowded. However, despite being a bank holiday, the train I boarded isn't less crowded at all.
