I am SO not getting into this handbag fight. But, Mr Bass is right.
Changing the position of the spring doesn't alter its 'springiness'. Only changing the spring for a 'springier' one can do that. Or, a system like Velos used to have where the angle of the shock itself can be changed .
Push one end of the spring, and the other end moves. Imagine taking the spring off, and holding it upright with the bottom resting on the ground. Now put a potato on the top of the spring. Measure the spring. Now put a book between the spring and the ground. Measure the spring again. Reckon the meaurement will be any different? The potato will be higher off the ground , but the spring will be the same length.
Replace book with swingarm and wheel. And potato with seat etc. Same deal.
