OK, nice. So, if I understand it right, it fixes the spacing like in:

     \startitemize[packed]
        \startitem whatever \openedupimath{\frac{1}{2}} whatever
        \startitem whatever $\frac{1}{2}$ whatever
        \startitem whatever $\frac{1}{2}$ whatever
        \startitem whatever \openedupimath{\frac{1}{2}} whatever
        \startitem whatever \openedupimath{\frac{1}{2}} whatever
    \stopitemize

between the rows where $ is used.

A related question: Is \startimath 1+1 \stopimath and $1+1$ the same?

I really like ConTeXt and want to use it (mainly for math since I work
in a maths department), so I want to understand the different
possibilities available.
