The problem is that you will get both streams mixed up.

No it tells VLC to bind to the specified address instead of binding to
INADDR_ANY. If the specified address is a multicast address, it also
issues the required IGMP request. But AFAIK his syntax is correct, and
will allow only those packets who are sent in unicast to the specified
IP to be decoded.

That's true.
