There is no notion of "joining to a feed" in the spec. A UDL will have one 
(or more) feeds, and receivers can relay through one of them. By "have two 
active receive-only interfaces", I presume you mean, two receive-only 
interfaces on the same UDL?

If I rephrase this as "when a receiving system has two active receive-only 
interfaces on the same UDL", does it capture what you mean?

I don't believe the situation is any different from a host with two 
ethernet ports connected to the same segment.

Routing will be done elsewhere. Section 6.2.1 describes how to forward MAC 
packets onto the UDL.
