I agree OBM but BA doesn't list the issue for anyone else but him, sounds like they think he has more of an issue with it the the norm. Or maybe they don't but they put it in there for a reason and since it's a question about him I had I am choosing not to dismiss it completely.
We might start asking the question at some point "why isn't Alonso being promoted?" and this one issue could be part or all of the reason why. It may not either but it's something to keep in the back of our minds.
