pulling the plugs allows the pistons to move freely and not build up any cylinder pressure therefore allowing the motor to free spin. this helps eliminate any excess force on any metal to metal surfaces, like rod bearings, until oil is pumped throughout the oiling system.
i know of small block Fords that you can take a drill with a socket, remove the distributor and actually turn the oil pump with the drill to fill all the oil passages / prime the oiling system before attempting to turn the motor over with the starter for the first time.
