With no plugs, there is virtually no cylinder/bearing load and the spin RPM is higher(vs with plugs), while 'light' starting the engine sees much higher cylinder loads and introduces fuel...the only thing seeing a consistent load is the valvetrain, and the pump pushes the same volume per revolutions(ie, not a variable-displacement pump), with some potential lose of efficiency at low rpm
Anyhow, everyone use what they are confident in and works for them...

Two vastly different scenarios. I do more engine builds than oil services!
