I dunno how special that case is, but there are lots of cases where mail passes through multiple layers of ARC signing mutations. I routinely get mail from Microsoft's farm with an ARC seal or two that has never been near a mailing list. Any time a MS user sends a message to one of my lists, it'll emerge with at least two ARC signatures.
