Callouts are never wrong. Any time ANY pilot is confused about what is happening, they should callout the confusion, so that it can be resolved.
first officer said "Yeah, you should have just let it be, captain knows what hes doing
How many times has that attitude led to an accident? Captain's are human, they get tired, they make errors - and nothing is better from an FO than saving you from making an error. I parked on the wrong stand just the other day (I am a multi-thousand hour Captain), and I wish the FO had said something before I turned in.
