Well because in the show they kept saying both Rahul-Roza are 16year old that's why i said it.And of course one can choreograph at whatever age but the level of that dance wasn't such that it looked like a young guy choreographed it.I mean if he was soo good that he choreographed such good dance at such a young age trust me he wouldn't have been eliminated.Anyways let's just say that you believe he is capable of choreographing that act and i dont.Let's leave it at that.
PS:I think Rahul is an amazing dancer
