My read on the history:
ES-330s and Epiphone Casinos were first released with short necks, later with longer necks. The people who made these guitars famous mostly played the short neck versions. The guitars weren't that popular after the mid 60s-70s due to stage volumes skyrocketing, and were discontinued. Since the mid 2000s, they have begun to become popular again as stage volumes came back down (due to modern PAs being favoured over enormous amplifiers). In response to this, companies like Epiphone and Gibson, bound by their duty to replicate the past instead of inventing the future, reissued the short neck version, which is more commonly seen on vintage recordings and stages.
Companies like Heritage, Eastman, Collings thankfully are willing to just build a modern take on the design without being bound totally by tradition.
