you need to get rid of the empty line

\definenarrower[whatever][left=1.5em]

\definestartstop
   [cslreferences]
   [before={%
     \startwhatever[left]
     \setupindenting[-\leftskip,yes,first]
     \indentation
     \GetPar
    },
    after=\stopwhatever]

\showframe

\starttext

\section{Some title}

\input ward

\section{References}

\startcslreferences

     \dorecurse{10}{\dorecurse{10}{This is a Test. }\par}

\stopcslreferences

\stoptext
