Whats the logic??

According to me, the logic behind the new leela not saying "Aye Aaaayeee" and saying "Are baba aati hu" might be that they may some day give us a surprise ....we may get to hear "Aye Aaayeee" instead of arey baba....and there..we would see the original leela... I am not saying ki aysa hi hoga...but this might be the logic...
What do u think might be the logic behind arey baba instead of aye aayeeeee?

The new leela looked like the older one in the dark...didnt she?

maybe the logic is that present leela carves a new niche for herself instead of trying to imitate the old leela as this wud also lead to unnecessary comparisions
