no, he is reading it correctly.
example: if i shout in your face for ten minutes laying on every despicable pejorative i can throw at you (fighting words) and you punch me in the nose, i can claim you assaulted me under the family car trip "Im not touching you" principle, however if you pull a knife or grab a chunk of concrete and come at me with murder on your agenda then i can defend myself under this moronically written law.
neither the stand your ground law, nor it's subsequent sections applies in the travon martin case.
zimmerman was stalking martin. this is an aaggressive act under every statue law and judicial ruling in the land. he followed martin, by car and on foot, cornered him and martin justifiably reacted in the manner that evolution has prepared, when flight fails, its time to fight. zimmerman being armed only upped the stakes, and trayvon lost his bid to defend himself.
zimmerman is a murderer. he had no right to follow martin, (i presume alternating between nervously fingering his gun, and pulling on his semi-turgid member), no right to corner him in a dark breezeway, and no right to confront martin and demand he justify himself. martin on the other hand had every right to resist the aggression of that asshole. regardless of how effectively he was kicking zimmerman's ass, zimmerman had no justification for drawing his gun and no justification for shooting martin in the fight HE started with his creepy stalking. for all martin knew, zimmerman was a pedagogue looking for a new victim, or a member of the klan scouting for a star for his next lynching. its a shame martin didnt dash zimmernman's tiny brains onto the pavement fast enough.
