I guess it comes from this part in pack-rul.mkiv, when you rotate the box by 90 or 270 degrees
context switches the width and height of the framed box (which is also used by \externalfigure)
but as you can see he does this first in \pack_framed_start_orientation and a second time in
\pack_framed_stop_orientation_odd.
\def\pack_framed_start_orientation
{\ifcase\p_framed_orientation
\let\pack_framed_stop_orientation\relax
\else
\scratchcounter\p_framed_orientation % weird .. why
\divide\scratchcounter\plustwo
\ifodd\scratchcounter
\swapmacros\framedwidth\framedheight
\swapmacros\localwidth\localheight
\swapdimens\d_framed_height\d_framed_width
\let\pack_framed_stop_orientation\pack_framed_stop_orientation_odd
\else
\let\pack_framed_stop_orientation\pack_framed_stop_orientation_even
\fi
\fi}
% why are the dimensions swapped again, this was already done above
\def\pack_framed_stop_orientation_odd
{\swapmacros\framedwidth\framedheight
\swapmacros\localwidth\localheight
\swapdimens\d_framed_height\d_framed_width
\pack_framed_stop_orientation_even}
