Yeah that part threw me a little, I assumed it was just a follow up once Sigurd was on the ground (and therefore not overly important as I intended to interrupt). Therefore I only imagined Gigue as attempting to throw Sigurd using his belt and his right leg as leverage. (Which obviously makes the sword thrust make more sense)

So are you saying that was a mistake, and Gigue actually meant to grab Sigurd's left leg with his right to perform a more standard take down? Considering you're attempting to pull Sigurd forward I'm not sure that would be any different than the belt grab, seeing as how Gigue is basically doing this using his strength alone rather than decent leverage (sort of like a reverse dump tackle.)

I am a little confused now though.
