I don't know because I know some "trainers" who train exactly that way. More than a few who don't even believe in saying "eh" or "no" or in any way marking the bad behavior. They just sit and wait for the dog to "get it right" so that they can reward. I watched one dog actually get up and leave the room - trainer told the woman to just drop the leash and let him go because to hold him back would be "punishing" his bad behavior. So she let him go. Called the dog. 2 or 3 minutes later the dog wandered back to where she was and she clicked and treated. I'm pretty positive the dog had no idea what he had done right. Or that he will ever have a reliable recall command but all that matters to the owner and trainer is that they don't "dampen his spirit" with corrections. Or they will tell the dog "sit" and if the dog lies down they say "good down" and treat anyway.
It's all about balance....
No kidding...You know, how easy it can be to tell apart the amature and the professional! The amature-s always tend to reinvent the bicycle by introducing new terms, moking old methods which doesn't suit their mentality and providing you with tricks. Alas, you would be wrong thinking the author doesn't have wide audience...
