What's the definition of "Ref node" in QRC extraction?

I know from the user guide it says "Ref node" specify the reference node (net) that QRC will use for decoupling capacitors during a run.

But what's the physical meaning for this "decoupling capacitors"? I think every parasitic capacitor should be explicitly specified by schematic/layout net names without specify this magic "Ref node".
