Can someone provide a better term than "equivalent"...
It's OK for the right ones, but not for the left ones.
(A=C) > B and (A=C) > D is "equivalent" to (A=C) > (B=D)
A > B and C > D is not "equivalent" to A > B, A > D, C > B and C > D
because first case allows A>B>C>D and second does not.
Did I miss something?
The last classification seems to miss the disjoint cases of undecidness,
maybe it should be a third class.

So, to avoid confusing the issues when studying the difference between undecidedeness and equivalence on voter behavior, I think weshould prefer an example such as this:
undecidedness equivalence A C A=C |\ /| | | \/ | | | /\ | | |/ \| | B D B=D
