Preloading only the right side shock?

I believe one shock is compression and one rebound, but not sure about that.

I guess it just seems to me that all the weight is on the preloaded shock/spring as the unpreloaded one is really just stretched to the same length as the preloaded shock but not supported by the preload adjustment. Maybe that’s not how it works at all and I’m thinking it works differently than it actually does?

I think what some folks are forgetting is the hydraulic left side preload adjustment was the only preload adjustment offered on the previous gen models..so it alone was designed to to support both shocks

Not really any different than the single leg swing arm BMW likes on their bikes. If that swing arm was weak, that wheel would be flexing on the axle. But the whole thing is strong, so it doesn't.
Similar the uneven set of springs on your bike. The swing arm is strong enough to not flex appreciably under the load.
Harley went even further with the shocks themselves. One resists compression, the other resists expansion. But again, the swing arm is strong enough to handle it.

The left side has a stiffer spring and different base internal dampening. The concept is used in many front fork assemblies where one is for compression and the other for rebound. While this isn't quite the same, its all in the spring rates, and internal dampening to achieve the intended result.
