Geography Final Jeopardy clue (30 Oct)--Was it correct? [unboxed spoilers]

[bibliophage]

I don’t recal the exact wording, but the question ran along the lines of “This continent is the only one where four countries come together at a point.” The expected response was supposed to be “What is Africa?” because Zimbabwe, Zambia, Namibia, and Botswana meet at a point in the Zambezi River. But from looking at my map, it looks to me like Zimbabwe and Namibia are separated by a few miles. Do they really meet at a point?

I said “What is Asia?” thinking of the area where Mongolia, Kazakhstan, Russia, and China come together. But on checking the map, I see that Mongolia and Kazakhstan are separated by several miles.

All i could find on the subject was this article from Encyclopedia Britannica, which says:

To the southwest is the thin projection of Namibian territory known as the Caprivi Strip, at the eastern end of which four countries (Zambia, Namibia, Botswana, and Zimbabwe) appear to meet at a point—a “quadripoint”—although the precise nature of the meeting is contested.

and this:

Botswana is bounded by Namibia to the west and north (the Caprivi Strip), Zambia and Zimbabwe to the northeast, and South Africa to the southeast and south. The Zambezi River border with Zambia is only several hundred yards long. The border along the main channel of the Chobe River up to the Zambezi is disputed with Namibia. The point at which the borders of Botswana, Namibia, Zambia, and Zimbabwe meet in the middle of the river has therefore never been precisely determined.
