Brown horse standing in the background while man in a white cowboy hat and blue long-sleeve shirt is walking off.
A horse is near a man who is about to ride it.
The man may be walking off to go away and not ride the horse
A horse in the background does not mean the man is about to ride it, no indication of where the man is walking, or that there is any other man near the horse who is about to ride.
The horse was in the background, not near the man. Also, if he is walking off then he is probably not about to ride it.
