Using \definepagecolumns[xyz][n=2] instead of \setupcolumns[n=2] and \startpagecolumns[xyz] etc. instead of \startcolumns etc. seems to do what I want, except that the columns of the last page aren't balanced any more.
Anyway, pagecolumns seems to be experimental. The manual says "Don't use page columns in production". as long as you keep in mind that they might 'improve' you can just use
