It's actually pretty easy to understand once you see how the oiling system was designed, that is, main bearing #1 has a direct feed from the main
oil gallery, but the for the oil to get to main bearings 2-5, the oil must first pass around the cam bearing journal directly above it.
Actually, I have a picture of it, but decided not to post it.
