It depends upon how the circles are calculated. If each circle
encloses all of the members of each group, yes. I doubt you would get
perfect separation in any real example, though. At the moment:
Hanukkah is finished,
Margashirsha Punima has just happened and
Christmas is coming up.
No matter how devout the adherents, I don't think you would find news
articles that only mentioned one of these festivals. Less facetious
groupings would suffer the same eclectic problem.
