\ifodd\realpageno
   this is 
\else
   rather safe
\fi

but indeed a twopass list is more robust; actually, you could use:

\setraggedparagraphmode
  {odd action}
  {even action} 

which generates the twopass entry too. Maybe I should have: 

\let\doifrightpageelse\setraggedparagraphmode

alternatively (atthe cost of more macros, since two pass lists are
implemented rather efficiently) you can use: 

\pagereference[here]\doifreferencefoundelse{here}
  {\ifodd\currentrealreference\relax a\else b\fi}
  {}
