Our Amsterdam friend is correct. The file plus rank disambiguation case is interesting as it was not mentioned in the FIDE rule book. (I don't know if the book has since been corrected.) But it was uncovered in my testing when I wrote the specification.
In the aforementioned position, only the move "Qa8xb7+" needs the special treatment.
