Joe is correct on both his points, though I think Greywolf was meaning that adjusting the preload does not repeat "DOES NOT" make your spring stiffer or softer, which is absolutely correct and an often mis-understood point... Good point too about the ratio of sprung to unsprung weight, this is why cruisers get away with cheaper basic suspension and dainty bikes like this one get lots of suspension adjustment threads on Internet forums....
As BJ said, adjusting the position of the rising rate suspension by raising the preload will make the rear suspension more compliant. This very important if carrying loads that lower the back end from a more typical static sag, or your ride will feel harsh. Over a year of ownership and solo riding I've found that I still like the rear end on my 2013 raised from stock position for that reason, and also the slightly quicker turn in.... I helped a friend with a Wee sort this issue a little while back, the preload had been lowered by previous owner to sort an "inseam issue"... when I tried it the ride compliance was awful compared to mine and while not sure if the actual shock was bottoming it seemed to be finding something in the rear suspension that acted as a travel stop. This was probably to prevent rear wheel contact with underside of seat, due to limited remaining travel. Adjustment up brought big improvement.
Same same the damping. If rebound damping is lacking, once you are a few milliseconds past the "bump" all that energy that your lovely, well designed suspension has absorbed will be fired back into your derrière, almost indistinguishable from the initial bump itself... Again, I have found over a year or so of breaking in the rear shock that rebound dampening has fallen off, requiring me to periodically tweak up the adjusting screw an 1/8 to a 1/4 turn at a time to maintain the same feel...
