Can't speak to this specific situation, but breeders are, in general, a very, VERY odd breed themselves. Particularly if you are into a niche breed, like my own Akitas, or a Mal, or something really rare like a Beauceron.
A lot of breeders look upon their dogs as "objets d'art". This is a very sad state of affairs. And these same breeders may pay more attention to conformation than temperament. Those who are producing dogs with an emphasis on working temperaments can be just as flighty.
When I got my first Akita I was forced to take a medium drive female of questionable temperament. She turned out to be 99% perfect, with the remaining 1% being "red zone" dog aggressiveness. Ultimately we made our bones in the very small Akita community by virtue of our performance in the competitive obedience arena. This lead to us being able to have the proverbial pick of the litter the second time around.
The bottom line is that there's no telling what any breeder might do or not do, whether it's for money, love, philosophy, or whatever.
