This, to my knowledge, is the first refereed paper to be published on Rosetta's observations of C-G (and it's free to access!):
The rotation state of 67P/Churyumov-Gerasimenko from approach observations with the OSIRIS cameras on Rosetta |

A contact binary would probably be more interesting, but I share your preference for exposure of fresh interiour material of a single object.
Once the outermost crust is lost, sublimation may progress faster in that area, resulting in forming the neck. The sublimation process of a prestine rotating cometary nucleus may start either near the equator for a spin axis parallel to the orbital axis, or near one of the poles if the pole happens to be directed towards the Sun near perihelion (skipping other options). Taking the equator version the rotation axis may change (or precess) due to a change of the axis of maximum moment of inertia due to preferred mass loss of the nucleus near the equator. |
