Close but not necessarily exactly that. Yes that is how coldcard accomplishes it. But my real point is I think it’s a bad incentive to need the seed in an unencrypted format in order to use the device. My guess is that in practice this means most people keep their seed nearby in such a manner it’s easy to steal, and generally, I think the more you handle your seed the more likely it is to get leaked. Coldcard does this in a stateful way where it is stored on the device in a manner where it is quite hard to extract, but the jade accomplishes this in a wholly different way with a blind signing oracle also making the seed essentially impossible to extract but you don’t need to handle or load the seed onto the device itself.
