Autofill algorithm seems to be failing

I was playing solo/duo with a friend. I was going mid/bot. He was going bot/jg.

The queue put him in the bot lane and autofilled me in the jg.

It didnt matter in our case, we could swap. But if that happens alot (witch it must, since it happened once), it means that alot of autofills currently happening could've been avoided. Please check the code.

Thanks.
