It's not called Double Down because it cost two cartridges. It's called Double Down because, when you look at the animation, it is literally your character jumping in the air and doing two downward slashes.

Similar applies to Lionheart. You might only be pressing 3 GCDs, but the animation shows multiple slashing attacks for each of them.

It's also a bit of a pun/reference. The attack is similar to one used by Seifer after he learns the truth of Ultimecia, but he refuses it and continues to engage in his wrong decisions, thus "doubling down".
