It's all to do with discharge coefficients and edge effects .... but nobody asked me yet so won't bore with the details .. other than they should and indeed do give the effects stated, basically changing the balance between bump and rebound but more significantly changing the pack ratio.
As for not being able to compress a fluid I can assure you that if you speak to people working in diesel fuel systems (for example) they will tell you that it is very much the case you can. Most operating conditions thrown at a modern common rail diesel fuel system the fuel is not only compressed but actually has higher stiffeness than the the metal around it, some pretty impressive bore dilations and profile changes for the designers to deal with.
