Writing this out made me think immediately of speculative execution. Interjection, similarly, saves "conversation cycles," by speculating about the future of a conversation and computing a response which occurs in the most likely branch. When the branching point comes, that's the interjection. It's either successful (moves the conversation forward) or fails (wastes time when the branch is not predicted properly).
