Yes, as far as it goes - but (and here I speak as someone who's written
a Rijndael implementation) having done AES-128, the incremental cost of
doing AES-256 as well is minimal.  The two can share almost all of
their code.

Unless, I suppose, you're doing it in silicon and hardwire in the shift
and rounds values, or some such.
