Hi,
if you want it to be placed exactly there in the text, that is not
really the way the new columnsets are meant to work. One shall be
aware of that with the new module, to place stuff where one wants,
there is a certain amount of manual work.
If you are willing to do some manual placement, you can do something like
\setuplayout[grid=yes]
\definecolumnset[example][n=3,page=left]
\definecolumnsetspan[wide][n=2]
\setupalign[mathbookpasses]
\starttext
\startcolumnset[example]
\input knuth
% this needs two columns:
TEXT THAT SHOULD GO BEFORE
\startcolumnsetspan[wide][c=1,r=34,ntop=1]
\startformula
\tau=\frac{1}{3} \left(1+\sqrt[3]{19-3 \sqrt{33}}+\sqrt[3]{19+3
\sqrt{33}}\right) \ .
\stopformula
\stopcolumnsetspan
TEXT THAT SHOULD GO AFTER
\input knuth
\input knuth
\input knuth
\stopcolumnset
\stoptext
But one shall also think one time more. If one has lots of long
formulas, then maybe a narrow three-column layout is not optimal.
