I think you are probably right--unless by some chance they are just the talent judges?
At about :46, you see someone who definitely looks like Taylor sitting with the rest of the kids in the saloon... And not at a spot behind the counter. I think it's safe to say that the Council is changed at the 50/50 mark.
Hey... Look what I found:
At about seven seconds, a blonde haired girl tells the kids to "knock it off". Taylor's sitting next to her, and Anjay's telling everyone to stop and that he has their attention. This is definitely after the Council change.
EDIT: I quickly found out how you add the videos to the post without having to open a new page. Go me.
