The check valve in the accumulator works to slow pressure bleed down once the pumps are shut down. It does not cap the system pressure, that is done by the fuel head. Excess pressure or volume is routed back to the tank.
The check valve in the fuel pump has a similar function in that it slows bleed down for easy starts.
As you have stated, when system pressure is checked the WUR is taken out of the loop.
