I thought it was pretty clear that the reason they fight the way they do is because they can anticipate the others move, making lightsaber duels a battle of endurance and waiting for your opponent to slip up. Also the whole "flail around like a drunken idiot" thing is a bit unfair, considering Darth Maul's techniques involve spinning and deception. Also Qui-Gon may be feinting attacks on one side to throw off his clash on the other since it's you know, a two sided weapon.
