Git Diagramming "The Weave"

Someone I know speaks in a reverse tree of sorts which actually does resemble a "weave", they start with various statements about the topic at hand without ever mentioning the topic, and eventually arrive at stating the topic near the end (hopefully). Sometimes I have no idea what they are talking about because they forgot to mention it until the very end when they have merged all their branches.

When it all merges, the payoff feels great. I'm a big fan of when it's used in comedy - https://en.m.wikipedia.org/wiki/Callback_(comedy)

Yeah but a callback is just a reference to a previous joke, not a tying together of unrelated points. Does the latter have a name? It seems so hard that I can't remember seeing it much.
