No, the main idea is that this isn't an app for creating podcasts with friends in real-time. While you might equate "asynchronous" with "not live", the actual contrast is between asynchronous and synchronous. The decision to stream a podcast live or make it available for playback later is separate from whether it's recorded in real-time or not. The "micro" aspect emphasizes the app's focus on short conversations, not extensive podcast recordings.
