I don't think I understand the change, and the documentation doesn't
seem to help.  It seems like now there are just two faces that are
used alternately, i.e. one face for odd-numbered groups, the other for
even-numbered groups?  If this is the case, why doesn't the
documentation say so explicitly?  And if this is not the case, what
did I miss?

And with the current implementation on master it is possible?  If so,
how?
