This is explained in section 8 of the document:

     There are two ways of specifying the second column — \MC (Math Column)
     and \NC (New Column). If \MC is used, the second column is in \math 
mode,
     with \NC it is in ‘text mode’.

Please send always working minimal examples like this:

\starttext

\startformula
     J^j :
     \startmathcases[distance=\spaceamount]
         \NC ω^0 \MC → 0 \NR
         \NC ω^j \NC → 0 \NR
     \stopmathcases
     \quad
     \startmathcases[distance=\spaceamount]
         \NC ω^k \MC → ω^l \NR
         \NC ω^l \MC → -ω^k \NR
     \stopmathcases
\stopformula

\stoptext
