While this is definitely within the time frame of a correctable error, is this a proper application of it? Aren't correctable errors more about what should have been -- or haven't been -- assessed?

Sound to me like you missed it twice. If the other official was 100% sure A-2 violated they should have blown it dead as soon as the T didn't get it. Once B secured the ball for the inbound you are eating that one.
