I was afraid this whole thing would turn serious.
On the one hand, I don't think the Jedi are going to hand control of the galaxy over to evil on the basis of fighting one against one duels.
On the other hand, I think the writers knew that audiences prefer main heroes to win on a one against one level. That's why they kept introducing deus ex machinas to turn the fight into a one against one between Gui Gonn and Maul, first by having Obi Wan put out of the fight by a kick that sent him flying down a level and then by the convenience of the force field keeping him out of the fight until it was over and then continued as a one on one between Obi Wan and Maul.
So there's a common sense factor but it's tempered by knowing what the audience generally wants.
