Its all about leverage on the sensitivity holes and tumbling action of the implement.A plow,for instance will try to tumble forward as the load becomes harder on the tractor which causes the 3 point sensing to slightly raise the plow depending on which hole the center link is in. Set in either the middle or top hole,that increases the weight on the rear tractor wheels giving the tractor more traction and less drag from the plow.The top hole responds more quickly and raises the plow more than the center hole does. Typically the center hole would be used for plowing and the top hole would more likely be used for a grader blade when you want to keep a constant load in front of the blade.The bottom hole rarely ever senses a load and should be used when depth or height of an implement is the only concern like when mowing.
