(Untested): \framed[align=normal,width=fit]{\startformula
\startmathalignment ... \stopmathalignment \stopformula}
math alignment is a display math environment, and must be inside a
\startformula ... \stopformula.
Two comments:
1. You know about \definemathalignment, right?
2. I think that this effect can be obtained more easily using
\startitemize[two,columns,a]
\item ...
\item ..
\stopitemize
but you might need to insert a negative \vskip (or \blank) to get matrix
to align with the item symbol.
