yet another sparsely documented feature ... in beta:

% tests/mkiv/pagestate-001.tex

\useMPlibrary[dum]

\setuppagenumbering
   [alternative=doublesided]

% new: \setupreferencing[doublesided=no]

% old: \somewhere{backward}{foreward}[label]
% new: \someplace{preceding}{backward}{current}{foreward}{following}[label]
% old: \atpage[#label]
% new: 
\doifcheckedpagestate{label}{preceding}{backward}{current}{foreward}{following}{otherwise}

\starttext

\dorecurse {20} {
     \placefigure
       [here]
       [fig:#1]
       {}
       {\externalfigure[dummy]}
     \dorecurse {20} {
         ##1: \atpage[fig:##1] /
         \doifcheckedpagestate{fig:##1}
          {preceding}
          {backward}
          {current}
          {foreward}
          {following}
          {otherwise}
     }
}

\stoptext

if okay, then it's something to wikify ... should 
\setupreferencing[doublesided=no] be default? (currently yes i.e. spread 
aware)

keep in mind that this kind of functionality once it kicks in (is used) 
can result in a few more runs to get thing right and that there's always 
the danger of oscillation as the text injected is dependent on the 
situation
