Why did Maul let Obi-Wan cut him in half?

Star Wars on Disney+

The first time I saw Star Wars: The Phantom Menace in 1999 (which should be named, The Rise of Skywalker and vice versa) I felt the lightsaber battle where Obi-Wan cuts Darth Maul in half looked like a lame scene because the Sith apprentice was just standing there and didn’t defend himself for like a whole second, but what if it was because Qui-Gon Jinn’s force ghost was slowing him down?

Master Qui-Gon was the first Jedi in a long time to be able to preserve his consciousness as a force ghost, but he seemed to work in audio mode only, but maybe he could touch and move stuff like Yoda and Luke did when they were ghosts. It probably looks that way because George Lucas may have rushed the filming, but I prefer to think it was Qui-Gon. Either way, it’s still my favorite lightsaber fight in all of Star Wars. What do you think? May the Force be with you.
