Because multiple is not False, but I am not sure about the logic.
No selection should still fail because it is not in the set,
i.e. multiple should mean 1 or more, not zero or more.

This is just a side effect of the above case.
Both validators are being enforced but IS_IN_SET is accepting an empty
input.
