It was a question to clarify because your original answer was ambiguous. No need to get defensive.
Even the rules you quoted talk about giving the appearance of performing without direction from the rider. Appearance is not the same as what’s actually happening.
Take your Grand Prix flying changes. The appearance is the rider is not communicating anything to the horse through the reins. The horse is fully aware of the communication that is coming through the reins, whether the rider is aware of it or not (usually not - at that level the subtleties of what they’re doing with their bodies is lost as the whole collection has become doing the thing). Claiming to not be using the reins to communicate at all is misleading to riders learning how to do things, and brings difficulties when they attempt to do nothing with their rein contact.
I do think this is an important distinction to make in a discussion about contact, which probably also should be distinct from connection.
Having the connection with your horse to be able to give the appearance of doing nothing to guide them is a fantastic feeling,and I agree that it’s something to strive for.
