Does the narrator call it swordsmanship or not? Cuz if it doesn't we Shanks fan were right about Shockwaves and not cutting thing which wouldn't make you a swordsman.
If it's swordsmanship we were wrong it doesn't classify as a swordsman, but I remmeber mihawk fans making fun of air bar thing when it was clear shanks or Roger didn't cut, I remember I did an edit on Roger hitting kaido damaging him like Shockwave and not cutting which to me explained why Oden was the only scar he had, I didn't expect shanks or Roger to cut Kaido
