I believe RFC1122 was written in the days when there was a one-to-one correlation between IP addresses and interfaces, and, you couldn't have one machine with multiple addresses on the same network. Obviously, also, we are talking about network multihoming, not host multihoming in a NANOG context. It is hard to perceive a situation where Host Multihoming would require coordination.

Other people use this term in very different ways. To some people it means using having multiple IP addresses bound to a single network interface. To others it means multiple websites on one server.
That is virtual hosting in a NANOG context. Some undereducated MCSEs might call it multihoming, but let's not endorse that here.
Unfortunately, this is a common and "standards blessed" way to refer to any host with multiple interfaces/addresses (real or virtual). For example, from the "Terminology" section, 1.1.3, of RFC1122, "Requirements for Internet Hosts -- Communication Layers," says,
Multihomed A host is said to be multihomed if it has multiple IP addresses. For a discussion of multihoming, see Section 3.3.4 below.
