I noticed this on Saturday when we drove along NC 222 to knock out a long chunk of it. Early on, it intersected with NC 42. I noticed once we got home that there is just the single intersection point there. But, there is a slight jog there. We were coming south, so we got to a stop sign, turned left, and then after the length of the gas station, we turned right to continue on 222. I pulled it up on Google Maps and measured it and it was around 300 feet. I don't know if that is below the threshold for doing two points or not. I will mention that a little further down the road in Fremont, there is a similar jog as it turns onto US 117 for a slight bit. The site has that segment at 0.10 miles, so that's not too much longer. I figured I would mention it.
