It's misleading indeed. This version of JPS+ is basically a preprocessing optimization - does graph compacting offline to compute a smaller representation that's faster to run guided search on. And of course there's a serious down-side: if the graph changes at runtime (eg. player builds a new door, or blows away a bridge) the preprocessing has to be redone, and it's not cheap.
