I don't think this "feature" should be supported, because even in your
R12 copy of Matlab, the | operator only short-circuits inside the
conditions of IF or WHILE statements.  So you can get different
results if you write

  t = f () | g ();
  if (t)
    ...

vs

  if (f () | g ())
    ...

and also in other cases with empty matrices.

Later releases of Matlab include mostly Octave-compatible || and &&
operators.
