Isn't 1 Link-layer multiplexing instead of multihoming? The rfc1122
mentions this explicitly as NOT being multi-homing:
<quote>
Finally, we note another possibility that is NOT
multihoming: one logical interface may be bound to multiple
physical interfaces, in order to increase the reliability or
throughput between directly connected machines by providing
alternative physical paths between them. For instance, two
systems might be connected by multiple point-to-point links.
We call this "link-layer multiplexing".

Besides that there is another configuration that is valid multi-homing:
3) a product is connected to 2 or more separate LOGICAL networks (i.e.
vlans). Since the logical networks are separate there can be no
assumption as to the address/subnets that may occur on any of the VLANs.
Since frames 'belonging' to one VLAN MUST be restricted to that VLAN
which is identified by the interface (source address).
This is not nescessarily a same subnet scenario but more an
'indistinguishable subnet' scenario.
