Overpass API and overpass turbo really are not the right tools for this job, as you cannot query yet for any non-closed areas in the first place (it's not implemented yet). This makes the whole endeavour very challenging. What you see in overpass turbo originates from the internal OSM -> GeoJSON conversion, but it's not possible to take that logic into account for any kind of query. I suggest to take a look at keep right! instead. It has a "non-closed area" detection. Osmosis Osmose QA probably has something similar. Example: [Keep right! example][1] -> will mark the following [way][2] as erroneous.
