Suggesting that a virtual short or virtual open, by itself,
doesn't cause reflections which is what I think others are
trying to say. Reflections associated with virtual shorts
and virtual opens always occur with some extra ingredients,
like physical impedance discontinuities, the very existence
of which makes one wonder if they might somehow be
associated with the reflections. Reflections always occur
at physical impedance discontinuities.
