I do know the *original* meaning was tagged on girls in ero-games who linearly progressed from tsun to dere. But that also begs the timeline problem.
To me, that's a limitation or shallow effect of the simple nature of ero-games. "real" personalities (or at least ones portrayed in anime) tend to be more complex with lots of cycling in and out of tsun and dere.
Heck, in Love Hina .... both Naru and Motoko routinely move from tsun to dere to tsun rinse/repeat multiple times even after they've been "won over" as it were.
