why not directly use the slidenumber

\def\SlideNumber{1}

command={\ifodd\SlideNumber\gdef\SlideNumber{1}\else\doglobal\increment\SlideNumber\fi}}

command={\ifodd\SlideNumber\gdef\SlideNumber{1}\else\gdef\SlideNumber{2}\fi}} 


command={\xdef\SlideNumber{\ifodd\SlideNumber\space1\else2\fi}}

\def\SlideNumber{\ifconditional\OddSlide1\else2\fi}

command=\ifodd\settrue\OddSlide\else\setfalse\OddSlide\fi

etc etc
