Your definition of nesting is slightly different from what's being used elsewhere in the thread: the article discusses the nesting of clauses, and the essential component of a clause in English is a verb. "in a skiff in the Gulf Stream" isn't a complete clause (and doesn't contain any) because there's no verb. "who fished alone in a skiff in the Gulf Stream" is a clause - to fish is the verb - but still not a complete sentence unless interpreted as a question. I'm sure you know that but the terminology isn't consistent between comments in this thread.
