quick hack that you can put in cont-new.mkiv

\def\handlearrangedpageTWOUP
   {\splitoffarrangedpagesTWO
    \ifconditional\arrangedswapstate
      \global\setbox\arrangedpageA\hbox
        {\box\arrangedpageA
         \box\arrangedpageB}%
      \setfalse\arrangedswapstate
    \else
      \global\setbox\arrangedpageA\hbox
        {\box\arrangedpageB
         \box\arrangedpageA}%
      \settrue\arrangedswapstate
    \fi
    \ht\arrangedpageA\paperheight
    \global\setbox\arrangedpageB\box\scratchbox}
