I have no idea. When I trained in Kyokushin, the sensei would occasionally give us rationale behind certain moves, but I don't remember ever doing bunkai (applications). At my shotokan dojo, I've heard that there are bunkai, but you don't get to them until the mid-level belts or higher.

(Yes, I find it particularly silly that we're doing kata with no real knowledge of any applications, but such is life at these dojos.)
