No. I had to look up the Samurai's appearance in all FF games before I posted that to make certain. Zeninage/Giltoss, Shiradori/Blade Grasp and "Iai" Instant kill abilities(single and multi-target) are the most commonly reoccurring abilities for the job. The Samurai is often one of the most devastating Heavy Frontliners along side the Dragoon because it has exclusive access to the slightly weaker but higher crit rate Katanas.
The Swordmaster of Bravely Default and Bravely Second is the only time the Samurai has focused on devastating Counter Attacks.
