That's the only thing I was explaining earlier doesn't really make sense, because essentially those Time Heists should cause branching timelines. But for whatever reason, it would appear that those events are just not timelines in themselves, but rather blisters on the timeline that don't actually continue into timelines of their own. The Ancient One scene was telling us that basically in returning the stones, they prevent a new timeline reality. It's a weird rule that's handwaved, but I think that's just the explanation.
