"With VRR, if the framerate is 40, for instance, the scanout is repeating 40 times per second (at least until you get to minimum refresh/LFC, where frame doubling occurs; the starting point of which varies per VRR method and/or panel tolerance)."

This is what I am referring to.

That's the same thing. 40 scanouts per second is obviously 40Hz. One scanout happens every 25ms. But each one of those scanouts only takes 6.9ms.

If it's still confusing, imagine two painters, Alice and Bob, who each paint one painting every hour. Alice needs an hour to complete each painting. So after she finishes one painting, she immediately starts painting the next. Bob, however, is fast. He only needs 20 minutes to paint one painting so you see Bob's finished painting faster. Then he does nothing and just waits for 40 minutes before he starts painting the next one.

Both painters are putting out paintings at a rate of 1PPH (Paintings Per Hour). But Bob finishes each painting much faster than Alice.

In the exact same way, 60Hz non-gsync, and 144Hz g-sync will do 60Hz when playing a 60FPS game. But 144Hz g-sync will finish each frame much faster.
