Yes, split horizon is the original term, which has experienced linguistic drift and is now just split DNS.
I think there is a useful distinction to be made between the various different ways that global names may have different meanings in different contexts. RFC 2826 talks about this a bit, and RFC 8244 comments further in section 4.1.1. Neither document attempts to enumerate the use cases, however. I think that split DNS is a specific use case, and does not encompass the whole phenomenon. If we want to talk about the whole phenomenon, this may not be the place to do it—I don't actually know of a term for the general idea. But I'm pretty sure that "split DNS" is not that term.
