What would cause this weird bearing wear?

So I just got back from my machine shop now. The crank was polished before being used, and that he wouldn't be surprised if the journal was a bit tapered. But he said that once he turned it he measured everything to make sure everything was true like it should be.

But because ive known these guys for a while they are going to help me out. He told me to bring in my block, rods/pistons and crank and leave them there for a few hours (to get up to temp). He will let me torque everything up and he will then measure everything to determine the bearing clearances. He said that he doesn't like using platigauge as it can sometimes not be as accurate. So he will be measuring it all how he does it. And he said he wants to help me out so he wont charge me! Ill have to bring them a case of beer or something lol

And to answer the other questions, the main caps were the right way (tang to tang) and the oil holes were lined up, the caps were also no mixed up.
