Mainly if people begin to use the API, where these things really count, they might expect to get to the same blank node id-s. You are right that this is not what we say, but this is what we suggest. And that is, didactically, wrong. Shane suggested to say 'Triples similar to the following will be generated:' and use _:X for _:john and _:y for _:sue. I think that is the minimum we should do.

Perhaps we just need to be a bit more verbose, specifically on that 
example, and say something like:

After processing, the triples similar to the following will be generated:

  _:john foaf:mbox <mailto:john@example.org> .
  _:sue foaf:mbox <mailto:sue@example.org> .
  _:john foaf:knows _:sue .

or

  _:x foaf:mbox <mailto:john@example.org> .
  _:y foaf:mbox <mailto:sue@example.org> .
  _:x foaf:knows _:y .

swapping 'or' for some text explaining why (ie have both examples rather 
than one or the other)

Best,

Nathan
