ANH: Kenobi would've survived his duel with Vader
Vader still tells Obi-Wan: "You powers are weak ... old man," but during their duel, Kenobi blocks Vader's sweeping lightsaber strike and ultimately traps Darth in a tunnel on the Death Star."But Ben manages to deflect the blow," can be seen on the script page.
As Kenobi runs to the Millennium Falcon, Luke later uses his father's lightsaber to help him after a blast knocks the old Jedi down. Luke and Kenobi get on board and the rest reads like the movie. Vader has his homing beacon on the Falcon and awaits to find out the coordinates of the Rebel base.

This is based off of a tweet by Peter Mayhew who played Chewbacca of an original script . Does that mean the battle can be seen as a stalemate? Thoughts?
