/31 linknets are common in the ISP world, it might even be /32 loopback of those devices, who knows.
I do agree that its bad but not for the same reason. On the diagram it looks like router IPs are their loopback IPs rather than the link IP, as we know a traceroute response comes from the interface the packet came in and that IP is used in the response. Seems like the creator tried to simplify the diagram and excluded linknets but made it more confusing instead.
