Yes.  Not all ways you can perform multi-interface capture are necessarily *useful*.  Think of it as being similar to the "any" device on Linux (the differences are that

	1) you can control options on individual interfaces separately;

	2) the interfaces can supply different link-layer header types;

	3) you have to specify the list of interfaces when you start the capture).
