Noob question: Is this (the Coversation) the basis of “Say Yes or roll the dice?”

Part of the reason I want to play in a PbtA game before I run any of them is that I’m not sure I comprehend this whole discussion. Yet. However, talk until something happens/triggers (say yes, etc.) makes so much more sense.

Am I even talking about the same thing here? Or is this a discussion for a different thread?
