But the topology given in the article shows three separate, non-overlapping /64s, one for each host/router. (Although one would assume that the router at least must have an interface in each subnet, even if that's not what the diagram shows).
One might hope these would be on separate VLANs, as overlaying multiple subnets on one VLAN would be a bit iffy. I've not spotted anything in the article other than the diagram to detail interface configs.
