What I think (hope) is intended here is, that if the same bnodeID is used in two graph documents in the same dataset, then that means that those two graphs do share a bnode. But what it could be read as saying is that whether or not they share the bnode is optional: they might or they might not. Which would be a very unfortunate reading.

agreed.

All improvements, but they still don't rule out the unfortunate reading. I think extra words are needed to do that, unfortunately.
