why demi why????????

I dont get why in Demi Lovato's new video for get back she replaces the word kiss with hold. It doesn't go to the rhythm well. To me i see no problem with the word. what the h*** is going on in her head? Dont get me wrong i love her solo album called dont forget. Its awesome i love it. But the video just plain sucks. Dont get me wrong again she is pretty and can sing but she barely moved in it. AND A BRIDGE IN THE BACK!!!!! GIVE ME A BREAK. I wonder if it means anything????!!!
