As Michael said, you're right, there is an error in the document. Indeed, the 4.4 example is what we intended; the other example is a mistake.

We'll get this fixed — might take a while as the process for modifying published W3C documents is not very fast.

Either that, or the triple can be added as an “incoming arc” in the linkset description.
