The scene definitely represents the evolution of both Kenobi and Maul as swordsmen. The scene does make sense, and there is a lot of background information that explains that.
Now, Maul before his injuries inflicted by Kenobi had a far different mindset than he did during the clone wars and rebels. During the duel of fates he was a calculating fighter. He controlled the fight, letting Qui-Gon lead him to the generator room. He allowed his adversary to do so, in order to weaken Jinn since he wouldn't be able to use Ataru properly in such a confined space. This combined with Ataru's weak defence allowed Maul to then go on the offensive once Jinn tired and dissect his defences.
After he lost his legs to Kenobi, Maul changed as a fighter. Sure he still remained a Juyo specialist, but instead of attempting to strategise during fights, he instead approached fights with blind fury.
Kenobi was an Ataru specialist but began studying Soresu after the duel of fates to make up for Ataru's main weakness, defence. He later mastered Soresu to its highest degree, which became his primary form. Windu called him the reigning master of Soresu.
Masters of Soresu have never had their lightsaber defences broken, but it is theorised that only Juyo could penetrate the defences of a Soresu master. Then again, Kenobi during the time of this duel did not practice much.
For the duel itself, I will describe what happens. Obi-Wan brandishes his lightsaber and puts himself in a Soresu stance. Maul then changes his stance twice. On the next change, Kenobi does something curious. He changes his stance to that of Ataru, the exact stance Jinn used against Maul, and the form Jinn and Kenobi himself used against Maul during duel of the fates.
Maul then attacks, instead of a defensive strike, Kenobi actually swings his saber to meet Maul's swing. An Ataru response instead of a Soresu response. After the second strike, which Kenobi aptly defends, Maul attempts the move he used on Jinn: moving his hilt up in order to stun, following with a killing blow. Kenobi however cuts the hilt of Maul's saber before he can finish the move.
My theory is that Kenobi adopted an Ataru stance in order to trick Maul into thinking he could pull off the same trick on Kenobi as he did Jinn. The fact that Maul did not think about what he was doing but instead relied on blind rage only made this worse for him.
That's my two cents on the fight.
