I am thankful to Aletheia Kallos for sending some very usefully information, which is being reproduced below;
"... as you probably realize google maps is doing their best but still cant be counted on for boundaries
the following best available maps suggest the tiny boundary segment between the tripoints in the chobe zambezi confluence should rather be drawn in the opposite orientation to that shown by google
so it may really be namibia & zimbabwe who will meet rather than botswana & zambia when everything finally gets straightened out for it is also true that several of the boundary ends that supposedly meet there are presently in some disarray or disagreement but even allowing for all that the prospective mini boundary is looking way shorter than 300 meters.
