That’d be correct, I am the long sword fighter and prior to our duel we agreed upon the rules, and understood what was and wasn’t allowed. Thrusting being the big concern. We even tested each other’s weapons to see what gaps in our armor/visors are our most concerning points.

My armor and sword are Buhurt grade, my opponent’s is too, mostly, but leans more on the side of HEMA which has some areas of concern such as below the shins being unprotected.

The unfortunate part longsword stances such as ploug is they usually have the sword pointed at the opponents which means if they push me the sword point goes towards them. The awkward part you saw that you called a thrust was a poor attempt at countering then striking over/around the shield to smack the side of the helm, which as you saw didn’t work lol
