Comment (by stumpc5):
I gave one possible general definition above. In that definition the poset
you give wouldn't be rank-symmetric.
I personally haven't seen examples where rank-symmetry was considered for
non-connected graded posets, and would be totally fine with having it
defined only for those. (Btw: at some point we agreed that graded means
that all maximal chains have the same length while ranked is given as
defined above.)
