Why the old bg score again?

Why die they plan Anjaan rishtey mein BG score again after the new one was released?

Is it because Sai is feeling that way now because she was the one who held his hands and was surprised she did that?

The first time this was played was when Virat tried to look at her through the wall of pillows, he started to feel this back then and she is entering that phase only now?

Because new verses emotions and situation were different , aur yeah toh tab play huva when virat asked sai which version of virat u like she plainly denied saying none , so may be because of that this version was played
