Looking again, it seems as if you might be right. Is it possible they're constructing the core up through the outer structure? Traditionally the concrete core shoots up first and you just bolt the surrounding steels onto it. But if you pour the cement around the center elements of the steel skeleton then the concrete core and outer structure become more of a single construct, which increases strength of the building significantly. I feel like they did that at 1WTC as well. Of course, I have no idea what I'm talking about so here's your grain of salt
