I'm not sure if the article is wrong in its interpretation, or if it's first paragraph is just imprecise enough that it suggested something completely different than reality to me.
When you say the core of the Earth has stopped spinning and is spinning in the opposite direction I envision relative to itself. Which seems impossible given the level of angular momentum involved.
Then I read this article:

Later studies refined estimates of the rate of that ‘super-rotation’, to conclude that the inner core rotates faster than the mantle by about one-tenth of a degree per year.

The subrotation would be the core is spinning slower than the mantle, not in the opposite direction that it used to be relative to itself.
So the change would be measured in tenths of a degree per decade, which seems much more plausible
