If the plug is left in on the downward piston stroke you will create a vacuum above the piston which will draw air from the crankcase into that space.
Piston rings are not good at sealing under these conditions, that is why rings have UP markings.
On the up stroke it will try and compress that air.
Its better to leave the plug out so that no vacuum can form above the piston and no air is compressed.
