Because the oil light will flicker on if the RPM is that low and the engine is warm, it's normal, try it with your own motor, turn the idle screw until the rpm is at around 400-500rpm (TBH it might struggle to idle and stall, like it has in this case) with the engine up to temperature and see.
When cold cranking the oil is so thick it would take no time to get up to pressure and turn the oil light out mate, although why your cranking long enough for it to do it I dont know?! Should have started by then! lol
