Yes. I'm not sure it can really be avoided, though. I'm trying to lift the usual restriction of having to predefine what the volume/subvolume/qtree boundary is and then disallowing links/renames between then. When all of a file's links are contained within the directory you're looking at (i.e. something that might be a subvolume under that paradigm), things look sensible. If links span two directories and you're looking at recursive stats for a dir containing only one of them, then you're necessarily going to have some weirdness (you don't want to double-count).
Making the primary/remote-ness visible to users somehow (via, say, a virtual xattr) might help a bit. The bottom line, though, is that links from multiple points in the namespace and a hierarchical view of file _content_ aren't particularly compatible concepts...
