[Kira had been speaking to another guy--some asshole just past Katou who's even now making his way quicker down the street--so he hadn't really been focusing on his friend-from-another-life before he spoke. When he does, though, he instantly has Kira's attention. The name rings true more than the other name that he's used for the last eighteen years, and he recognizes that voice. Astin--no, Kira--starts, sitting up straighter on the the low brick wall he's been perched n top of.
The guy in front of him doesn't actually look like Katou for a moment, but honestly--he could stick his head in a paper bag and Kira would still know that voice. It stirs with it more memories than he can untangle (beating Katou up the first time they met over a fucking lighter, smashing someone's car lights while drunk off their asses and running away laughing before the cops could show up, Katou stoned as shit while his dad died, pulling him off Setsuna from a fight, throwing up cables, dying)--admittedly, it's a lot to process in just a few short seconds.]
