I am not the author and haven't had time to fully review the spreadsheet they provided. After an initial look I think he is referring not to the kubernetes specific networking support but the GCP networking. From the spreadsheet alone GKE has support for cross region load balancers. The author also points out cross region networking. I don't know the exact advantage the author sees with cross region load balancers since you can only deploy a GKE cluster to a single given region. The GCP LB's are really nice though in that traffic enters Google's network at the closest location to the user and then travel within Google's network, which is wicked fast. I have not played around with federated clusters in multiple zones so don't know how that would play out either. They may also just be referring to just general networking from the providers. With the first two points they at least make mention in the spreadsheet of it though. tl;dr: not sure what the author meant but here here is some food for thought on it.
