Anywhoo back to your plate.

The pivot just supports the truck, it doesnt change the steering.

If you were able to only adjust the pivot angle without the need to shim the plate side cushion to adjust the height up/down and it resulted in change to steering, I'd be far more inclined to believe that your "caster" adjustment is solely what is making the difference.

The way the cushions interact with the trucks yoke matters alot in how the truck itself behaves. When you adjust the height of the cushion you cant help but change the way pressure develops on the cushions. This is what changes the steering feedback.
The pivot adjustment doesn't change the steering, correct, it is the anchor for the changes by shimming the upper cushion. It is the beginning, "pivot point" that doesn't change while the truck's angle is changed.
There are changes in cushion setup that others have not been investigated by many. Biasing on cushion setups work on DA45s. Using different duro cushions above and below the yoke definitely produces different results in handling, it just doesn't work on other plates. I need to come up with a descriptor on "other" plates. The changes become even more obvious with taller cushions(more than .400).
Shorter cushions minimize a lot of the changes but the changes do still affect handling.

Edit: also, if you are of any weight at all and running softer cushions, your weight alone varies the caster from loaded to unloaded plates, as in sitting on the table or being stood on.
