The lateral bend always corresponds to a circle of a certain size. This is the reason why the Spanish Riding School in Vienna used to ride a volte in the first corner of the long side to create the necessary bend before starting a shoulder-in or a half pass.
If you picture your horse being aligned on a circle line, with the left pair of legs on the left side of the line, the right pair of legs on the right side of the line, and the spine forming a segment of the line, you can see that the lateral bend has to increase as the size of the circle diminishes.
The smaller the circle, the more the horse has to bend, and the more the inside hind leg has to support the body mass and flex its joints. In other words, there is a correlation between bend and collection as well as circle size and collection. More bend requires a higher degree of collection, and a tighter turn requires a higher degree of collection as well.
