I'm not sure I exactly agree with that. Though I have not shown in agility, herding... I can somewhat tell if a dog could be a prospect in that particular venue. Based on energy level, confidence and the list goes on.
I would never, ever claim to know if a dog has herding instinct. Chasing a ball in the yard or running in big circles around other dogs does not a herding dog make. My landlords Sheltie chases cars like nobody's business, does he herd? Nope. He doesn't even acknowledge the sheep's presence, even flighty sheep. So until a dog/puppy has been introduced to and actively shows interest in livestock, you can not assume they herd. Even dogs from herding lines don't necessarily herd.
