Comment (by komzpa):

 ST_3DIntersects in GEOS backend is a plug for ST_3DDWithin(geom, geom, 0):

 https://github.com/postgis/postgis/blob/dd281b1e57b590c0339271cedbf5feaf84049cc4/postgis/lwgeom_backend_api.c#L153

 We are going to remove it during #4258 and (probably) rename to
 ST_3DSurfaceIntersects. May it happen that surfaces of ac intersect, and
 surfaces of ab don't? If yes, then it works as expected codewise, and
 we'll untangle this in 3.0 by renaming function.
