The answer is yes it will (so the answer to your > question is: no, not true).
I'll try to answer from a different perspective. If the destination is a subnet-local multicast group, it may not reach all of the nodes on a link. This is because nodes, currently, do not even know of such a multicast group much less join it. In theory it should go to every node, I think.
