You never know when tex will break a page unless you are explicit so you 
typeset the status too soon.

\setuppagenumbering[alternative=doublesided]
% \setuppagenumbering[alternative={singlesided,doublesided}]

\starttext
     \dorecurse{200}{
         \dontleavehmode\signalrightpage
         \doifelserightpage{RIGHT}{LEFT}
         \doifelseoddpage  {ODD  }{EVEN}
         \par
     }
\stoptext

The rightpage check combined with putting a signal at the spot where you 
test will work ok.

The odd/even test works as expected when you're in the page builder 
(wrapping up the page).
