I quite agree Steve, pressure is generated by resistance to flow and you only want as much as is needed to deliver the oil where it is required (but no less!)
In such a case where oil is forced to flow through a small orifice or venturi, the sudden acceleration of flow and subsequent pressure drop might well result in aeration of the oil, which is not a good thing at all.
In any engine, splash or pressure fed, a sudden unexpected high pressure reading is cause to stop the engine immediately and investigate (though in the case of your trials car I can easily understand that the cause was not spotted).
