This is another small detail of riding that has larger consequences, over posting. When we casually look at the left image, we see a well turned out horse with a rider posting the trot. When we look deeper with an eye of critical horsemanship, we see violations of the principles of unity. The horse and rider do not share the same balance and unified movement.
Some riders may think this is a meaningless detail, however, without the unity of balance and movement, the horse and the rider are moving and balancing separately. The result is the horse must compensate for the rider's separation or disunity. This forces the horse to focus on coping with the external force of the rider's movement instead of on their own movement and balance.
This rider is over posting, meaning pushing their body upward with unnecessary excessive force. The rider's seat is quite high up out of the saddle with the rider's movement out of sync with their horse's movement by the excessive posting. Over posting is contrary to Henry Wynmalen's important axiom, "Let the horse move you".
The blue line is an approximation of the shared or unified center of balance when the rider is over the saddle where unity is best achieved. The pictured over post launches the rider's body ahead of the blue centerline, placing the rider's body mass and weight onto the forehand. The tilt of the rider's head adds to this forward imbalance.
As the rider disrupts any possible unity with their over posting, the resulting disunity of balance and movement can be seen in the shortened reach of the horse's hind leg illustrated by the yellow line. With the rider's weight shifted onto the forehand, the horse must compensate by limiting its hind reach. An oddly extended and imbalanced stride is the result of this forward imbalance.
While the forced energy of an over post is hardly ever addressed in lessons, it can easily lead to an unbalanced horse that can more easily stumble or sometimes fall. Ultimately, if this is how a horse is regularly ridden, the chronically imposed imbalance and separation from the rider's movements can ruin a horse's naturally balanced striding.
The lack of unity seen in this example of over posting is a very common horsemanship problem today. Unity of balance and movement is essential whether you ride English or Western and in a discipline. Every rider can benefit from increasing their awareness and skills to achieve the oneness with their horse in unity.
