Is it possible for a dog to be working in Fight Drive, but as soon as the bite work is over the dog is wagging his tail and getting petted by the decoy?

My name is John and I belong to a French Ring club here in California and our club decoy says that he trains all his dogs in Fight Drive. Well, after I purchased your tape on Fight Drive (Bark and Hold for Police Service Dogs) I'm wondering if his dogs are just playing a mean game of tug of war, because as soon as the decoy works the dogs they come right up to him and he pets them and gives them love. He says that they are working in Fight Drive, but it does not look like the dogs really look at him as a fighting partner.......is it possible Mr. Frawley for a dog to be working in Fight Drive, but as soon as the bite work is over the dog is wagging his tail and getting petted by the decoy?? This does not look like Fight Drive to me!! Thanks in advance.
