That's exactly what it means. But if you didn't know that you can look at the last oscilloscope screenshot; as you can see, it's set to 200 nanoseconds per division, and it's pumping out bit transitions quite precisely every 50 nanoseconds, and 10BaseT uses Manchester encoding, so that gives you 10 megabits per second.
I think GP might mean what sort of data throughput would be achievable, but that's also trivially 10Mbps with suitably trivial data, and sending easier than non->/dev/null rx.
Really more a question of what you try to make it do with the link, but it would be fun to see it do some very basic routing/firewalli g for example.
