The spacing is different in cases - TeX also has such a variation. Specifically, there is extra space before the conditionals.

In addition, it seems \startmathcases ... \stopmathcases is not working with UTF-8: in the example below, the ω’s on the second line, after the arrows, disappear in my PDF.
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’.

\startformula
J^j:\startmathcases\NC ω^0 \NC→ 0 \NR \NC ω^j \NC→ 0 \stopmathcases \quad
\startmathcases \NC ω^k \NC→ ω^l \NR \NC ω^l \NC→ -ω^k \stopmathcases
\stopformula

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
