Surely though if one pump drops to min fuel pressure then the same happens with two, after all it is about pressure and supply. Could one pump not supply 100% even if one fails?
Yes tou could, I have it on mine, sensor on the fuel rail.
If you are reliant on needing 2 then the problem will often occur at full chat mid corner, one pump drops out, lean mixture, one pump tried to keep up, with just one pump it the pump seizes or practically stops then (fuse should blow) car will cut out from no fuel.
