I wouldn't read too much into it, it's clearly Gbps. The authors are just sloppy with capitalization. They also elsewhere talk about iperf having "128 kb" buffer which seems unlikely, and the throughput graph says "gb" where the text says "GB".

And then there's "iPerf" and "PING"...

If it were gbps then that's certainly weird. I consistently get way better network performance in GCP than in AWS.
