They stack with each super yes. Atk goes to the SA multiplier, DEF goes to the DEF stat.

The thing with raising ATK with a super is that it doesn't get added to the ATK stat, but rather the SA multiplier, so it takes longer to see an actual noticable difference than if it was added directly to the ATK stat, in which case you'd notice a difference almost immediately.

DEF on the other hand goes directly to the DEF stat unlike ATK. So you'll see an increase to you DEF stat every time you Super. Plus boosts from SA's are separate calcs, so you actually get more DEF than what's actually listed, (the actual amount depends on your current buff)

Regardless, you are correct in that both buffs are permanent and stack with each super.
