It's quite common tbh. Two different companies, one provides the last mile, one provides the customer service layered on top. It adds a lot of flexibility, for instance in this case the person was on-net for Verizon, but what if they were not? Then it wouldn't change at all, just the first NID would be a different provider than Verizon.
