Question about the gif—to me it looks like the phase transition is more like:
4++- to unstable 5+- to 4+- to 5-(Unstable 5+- seems to have similar loss to 4+-).
Why do we not count the large red bar as a “-” ?
Good question. What counts as a “-” is spelled out in the paper, but it’s only outlined here heuristically. The “5 like” thing it seems to go near on the way down is not actually a critical point.
