Of note, there is no 'pump' unless you're treating the pistons as pumps.
Simple (2-way, 2 position) solenoid valves come in two flavors, normally open and normally closed (there are exceptions such as latching).
It sounds like pulling the fuse tells the electrical brain box to default the system to command the valves closed. This is probably for 'safety' to ensure body roll/stability is maintained under a simple electrical (fuse) failure case.
Pulling the plug at the solenoid/accumulator box disconnects the solenoids from the brains and they default to their normally open state.
Driving at a 6" square curb at 10 mph might be harsher than hitting that same bump at 60 mph depending upon where you are at in the natural frequency of the system (sometimes it's easier to drive faster and things smooth out than drive slower and things go bumpity bumpity).
It would be great if someone could take their phone (with a good mount), and run some tests over the same courses (whoops, washboards, etc.) to quantify harshness (vibration/shock mostly) along with body roll etch with the system on and off for comparison.
I’m working on some comparison videos for website. But my setup is not fair either.
