It turns out that the list is not exactly accurate, as first reported by Ringside News. RSN reports that the initial report on the listing is something that was put together by Bruce Prichard and Ed Koskey. A WWE source stated the following: "Then, every few months, Vince does not like the way it looks and he moves names around."
The source added that the report is "supposed to be the order of who is number one and number two and down the list, but it’s subjective and nothing is official unless Vince signs off on it" and that it's not definitive and everything in WWE has to get Vince McMahon's blessing.
It was also noted that the writers' assistants update the rosters on a daily basis and while the leaked list is a good reference, it is not "an accurate look inside the company." Ricochet is a recent example of the constant changes in WWE. A couple of weeks ago he was slotted as the number 2 babyface on SmackDown and then he wasn't booked for WrestleMania.
At this point, it looks like WWE is all in with Cody's push as one of the top names on the roster. He is scheduled for a rematch with Seth Rollins at WrestleMania Backlash and things seem to be trending towards an eventual shot at the WWE Universal Championship. Of course, plans can always change in WWE and Cody is considered a top star right now but that may not be the case in 6 months. His treatment in WWE will be interesting to keep an eye on.
