I think what @cARloTB is saying is that your sensor will be reading the engine's best pressure. Depending whether it is on the feed to or return from the cooler it will read the maximum pre- or post- cooler pressure.
If you want to read what the engine's oil pressure condition is, he is suggesting read it in the 'worst' location where it will be the lowest.
In an ideal world you'd read it at the filter housing (i.e. directly off the oil pump) and at the cylinder head with some high tech output of impending doom.
