.. it was not really a minimal example ...

\showframe

\starttext
     \topskip4cm
     \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page
 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
     \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page
 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\stoptext

so, you need to wrap it, like

     \startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
     \startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup
     \startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
     \startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup

and not make it 'sort of text that breaks or not across the page'. Now 
it is an interesting question why ... (spoiler: nice animation:)

\starttext
     \topskip4cm
     \dostepwiserecurse{0}{360}{1}{
 
\rotate[rotation=#1]{\externalfigure[A3page.pdf][page=1,width=\textheight]}
     }
\stoptext

so we probably cross some threshold with some angles and because these 
are basically lines, we then get an interplay woth topskip, maxdepth etc 
(which normally goes unnoticed)

the good news is that you can play with it because rotate is normally 
configured for inline usage (so we get depth and height) you can use the 
location parameter to do otherwise:

% normal default depth fit broad high middle

\starttext
     \topskip4cm
     \dostepwiserecurse{0}{360}{1}{
 
\ruledhbox{\rotate[rotation=#1,location=high]{\externalfigure[A3page.pdf][page=1,width=\textheight]}}
     }
\stoptext

irr it's actually shown somewhere in a manual but the source also has this

% \dostepwiserecurse{0}{360}{10}
%   {\startlinecorrection[blank]
%    \hbox
%      {\expanded{\setuprotate[rotation=\recurselevel]}%
%       \traceboxplacementtrue
%       \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=depth] 
{\ruledhbox{\bfb  (depth)}}}}%
%       \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=fit] 
{\ruledhbox{\bfb    (fit)}}}}%
%       \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=broad] 
{\ruledhbox{\bfb  (broad)}}}}%
%       \hbox to 
.2\hsize{\hss\ruledhbox{\rotate[location=normal]{\ruledhbox{\bfb 
(normal)}}}}%
%       \hbox to .2\hsize{\hss\ruledhbox{\rotate[location=high] 
{\ruledhbox{\bfb   (high)}}}}}
%    \stoplinecorrection}

% \def\Test{\ruledhbox{%
%     \def\DemoX{\vl\kern.5\emwidth\vl}%
%     \kern\emwidth\ruledhpack{\green\rotate[rotation=20] 
{\ruledhpack{\DemoX}}}%
%     \kern\emwidth\ruledhpack{\blue \rotate[rotation=0] 
{\ruledhpack{\DemoX}}}%
%     \kern\emwidth\ruledhpack{\red  \rotate[rotation=-20] 
{\ruledhpack{\DemoX}}}%
%     \kern\emwidth\ruledhpack{\green\rotate[rotation=200] 
{\ruledhpack{\DemoX}}}%
%     \kern\emwidth\ruledhpack{\blue \rotate[rotation=180] 
{\ruledhpack{\DemoX}}}%
%     \kern\emwidth\ruledhpack{\red 
\rotate[rotation=-200]{\ruledhpack{\DemoX}}}%
%     \kern\emwidth}}

% \startTEXpage[offset=10pt,align=middle]
%     \setuprotate[location=fit]     \Test \par 
{\infofont\setstrut\strut fit}     \par
%     \setuprotate[location=depth]   \Test \par 
{\infofont\setstrut\strut depth}   \par
%     \setuprotate[location=broad]   \Test \par 
{\infofont\setstrut\strut broad}   \par
%     \setuprotate[location=high]    \Test \par 
{\infofont\setstrut\strut high}    \par
%     \setuprotate[location=middle]  \Test \par 
{\infofont\setstrut\strut middle}  \par
%     \setuprotate[location=default] \Test \par 
{\infofont\setstrut\strut default} \par
% \stopTEXpage

so, not a bug but a features (that code hasn't been touched for ages, 
apart from maybe some lmtx interface adaptation), and if it's not in the 
wiki .. you know what to do now
