well, not part of api, noticed, drill up, need call chart.drillup(). drilldown, it's bit different , depends want drilldown.

in short call method: chart.xaxis[0].drilldowncategory(category_index);, see: http://jsfiddle.net/vncnwd66/2/

however, there 1 limitation: can't drilldown second level of a, second level of b. first need drill up, drilldown second level.
