    16 The reason is the ST_ShortestLine is a line with the shortest distance.  Both a single point and a invalid linestring having two points the same have a distance of 0.  So it is the shortest distance.  A null would return a null which isn't technically right because that would mean we don't know the distance, but we do, it's 0.
