The church doesn't quite work that way. The only group that has authority for policy is the first presidency and quorum of the twelve. They only make decisions when they all agree, so no one is going to go out and say something and then have it not backed up. Could if be a miscommunication, maybe but not very likely. Also look up the scouting experience of the president of the church. His name is Thomas S. Monson. Someone that connected is not likely going to be misunderstood.
I think this vote is just the final nail in the coffin. It would be easier and cheaper for the church to just run their own program. They also would not have to worry about getting sued and not having BSA back them up, which in my opinion is what will happen.
