It isn’t riding in ‘mistake prevention mode’ and keeping the horse’s head down by whatever means. But it is the ‘human trump card’ in the ‘got it/lost it’ game that each rider learns (we hope) to play with her horse. This concept suggests a viable ‘it’ that the rider wants to get back to - but this is not a foregone conclusion. This involves water going through the horse’s hoses (from his hind legs over his top line) without being dissipated, deadened or deviated, and a rider who does not fall into the traps of leaning back, growing tall, lifting her chest, pushing in her stirrups and pulling on the reins - in short ‘water-skiing’ and encouraging the horse to be her ‘motor boat’.
