Maybe, maybe not. I believe there is more depth to the whole 'Naming Cermony' and let's look at Vexen, the arguably oldest member of the org. He moves by leviation (Much like Xemnas) due to being so old, making him move more efficently. Then look at the lesser nobodies and their insane flexibility, and then remember your most frustrating moments with Vexen's Ice Blade attack and how that relates to the lesser nobodies. (Ansem is arguably the same age as Even, perhaps even younger)
