Still alot of twirling on Dooku's part. He outranges Yoda by alot. And when they go sword to sword. You can clearly see that he's making contact with the lower half of his blade, and not the sweet spot, 3/4 way towards the upper end.

Here he still swings too close to his body. In any form of sword art, the most respected idea is the range between the blade and the person. A rational opponent would just take a step back so that Dooku's short swings would miss while being at ideal range to strike. The problem with swinging so close to the body is that there is no leverage. Which is sometimes acknowledged in the duels when they want someone to win, like Dooku's dispatching of Obi Wan, and other times ignored like their fancy but empty flurries.

Anakin starts with a wild telegraphing swing here that should have gotten him decapitated.
And finally Dooku gets decapited because he leans forward even though he's so close already, gets knocked off balanced and his wrists sheared off from the shortest part of Anakin's blade.
Wuxia adaptions don't count though. Jin Yong is pretty descriptive when he describes his fights, none of the adaptions have cared too much about following his play by plays in their choreography. Whereas Star Wars' choreography is as the creator envisioned.
