No expert either, but what you suggest is hypothesis.

Article reports some new evidence that seem to support it.

Not every seemingly obvious hypothesis is true.

My personal favourite at-first-counterintuitive law of nature: in orbital mechanics, to catch-up, speeding-up does not work. Speeding up (1) changes the orbit, (2) elevates the orbit, (3) higher orbit has lower speed. (Excluding trivially close distances)

So how do you catch up then?

Slow down and take the shortcut.

Slow down to get into a lower orbit, where you will overtake your target. Then speed up to get back into the higher orbit where the target will catch up with you.
