This is a classic example of the RO attempting to take away the Vet’s rating. They are not well versed in this and usually screw it up. In this case the vet had appealed the action and ended up having the BVA restore the rating. This is rare and doesn’t happen very frequently. But it does happen ,which is why Mr. Murphy wrote a book of laws concerning it.
