Re: Qui Gon etc...
Not really, they had both come to the same conclusion as to where the Stormtroopers would go next.
It wouldn't take a rocket scientist, or a Jedi Knight for that matter, to figure out what would become of Luke if he arrived while the imperial forces were still present. That's why Obi Wan urges Luke not to go.
Also Obi Wan had already taken stock of the scene as soon as they iscovered the crawler and deduced for himself what had transpired. This was not the work of the Force, simply of a deductive mind, maybe aided by the force but not through any detection of Owens death.
