If anything, I bet they're connected at the neck right below where the head is connected and hidden by the ponytail. This would allow the head "full" movement while not making it look like his hair isn't attached to his head.
And regarding the articulation, I'm pretty sure they said that the figures are basically made directly from the game models.
