^ The centipede tails were a product of Kaneki's torture at Yamori's hands, which took place several years before the current time. It was just the way his half-kakuja manifested at that particular time, with that particular trauma still fresh. It's evolved quite a bit since then, manifesting in the armor we see now.

As for using the kagune with the kakuja, that's not a unique trait. Yoshimura did the same during the Owl Suppression.
