Their figure 4 still shows that humans and chimps diverged more recently than gorillas and humans or gorillas and chimps.
Your “logical impossibility” is the reality that Biologists must deal with. Humans and chimps are more closely related in DNA than either is to a gorilla.
You have yet to find a source that doesn’t end up concluding the exact same thing, as Figure 4 from your latest source shows.
That's the current evolutionary dogma. However, more and more Evo scientists are using the data to draw alternative evolutionary scenarios which show humans diverging from gorillas, and still others that have humans diverging further up with the common ancestor of both chimps and gorillas, with chimps not even being included in the same branch with humans. In other words, human evolution is a subjective mess that is getting worse by the day. And the reason is obvious...life resists evolutionary explanations because God created all life approx. 6,000 years ago, with each creature reproducing after its own kind, just as it is described in the Bible.
