It is possible for an artist to be able to control their VEVO account considering it may be their only one [account]. So this could have been Christina's doing, but 85% of the time it is her team that controls the account. We'll never know though.
Let's look at this way, RCA may be ready to jump on Demi whenever her contract with Hollywood Records is done.
I'm just glad she/they chose the top five songs from the album though
EDIT: I didn't close this
