Can someone break down this picture for me and talk about what is happening to cause this in the photo?

An extended trot is supposed to be an extension of the stride of the horse. In order for that to occur, the entire frame of the horse, from tail to poll, must be allowed to extend. That is what a “lengthening of stride” is.
The toe of the horse cannot land any further ahead of the vertical line of the face of the horse, or in some cases of less collection or extension, in front of the nose of the horse. When the horse’s face is held in as in the photograph of the gray shown, and the legs are thrown forward of that vertical line, the leg must actually drop back before the toe can touch the ground again to carry weight. That is why it is an inefficient and incorrect form of an extended stride. It is a false extension.
The toe-flipping occurs because the horse is really trying to do what his rider is asking (note rider’s legs with spurs on horse’s sides), but his rider is not allowing the spine, including the neck, of the horse to extend. This also means that the flow of energy that should be being created from the rear end of the horse being fully enaged is not being allowed to come through the back of the horse into the bit and hands. The flow of energy that should be being created from back to front is being constrained and creating tension that stops the horse from “floating” into a large, full, correct long strided extended trot.
