An algorithm was presented in  for unfolding orthostacks into one piece
without overlap by using arbitrary cuts along the surface. It was conjectured
that orthostacks could be unfolded using cuts that lie in a plane orthogonal to
a coordinate axis and containing a vertex of the orthostack. We prove the
existence of a vertex-unfolding using only such cuts.
