This is 4 minutes and 12 seconds after WOW (take off) and they did not have the AoA disagree option I believe - pretty strange for a reasonable time Captain and low total time cadet to have a "snap" on exact words at that stage of flight.
The Alpha Vane warning light is part of the anti-ice system. It illuminates if the AOA heat malfunctions. It has no bearing on an actual AOA signal failure, only a failure of the vane heating system.
