It's quite a hard thing to visualise, but I think you're getting it.

Consider it this way.

The pressure drop across a block at any point in a loop of identical components will be the same, since the flow rate will be the same, yes.

So while there may be a greater pressure at the block inlet by situating the block right next to the inlet, but the pressure at the outlet of the block will also be considerably higher than if the block were at the tail end of the loop. The relative difference between these two values should not change regardless of positioning, and it is the pressure difference, essentially a pressure GRADIENT which causes flow, much like a temperature gradient causes flow of thermal energy.

Hope this helps
