I mostly like that, but I quibble with "source of the query". It's really "depending on some factor apart from the name, class, and type of the query. For instance, the answers might differ according to the source of the query." EDNS client subnet is another example, but I've also seen things based on authentication (SIG(0) or TSIG). Effectively, every "DNS tricks" service on the public Internet is also a kind of split horizon. I think we should include all of "split DNS", "split horizon", and "split brain": they're all terms I've heard and so we ought to make sure they're both included.
