Having a software defined networking spanning across regions and failure cascades across regions are two different things. There's nothing preventing a vendor from presenting to you a single network, while they are actually distinct networks.

Having distinct networks in different regions encourages you to architect your application in a fault tolerant way.

Or the contrary. In most cases there is something to synchronize between regions, like a replica of the data.

With difficult interconnection of regions, it makes it somewhat harder to do, and it can easily end-up with "meh, AZs are good enough".
