These are just my thoughts that it was just the contestents who did not know anything but otherwise it was all planned.
If you guys watch video again you will notice that when evryone was shouting mini was telling something to Anuj and Amey, probably she was telling them that judges will come back with rematch suggestion and how they(Anuj & Amey) have to react, otherwise what was so important at that time that she have to whisper in their ears.
Well! As I said this is just what I think.
