retcon - http://en.wikipedia.org/wiki/Retroactive_continuity

I assumed she was talking about using chaos theory or any other sort of other excuses for branching a timeline as a work around to retcon. Technically, it's not retcon because while it "contradicts" the other chronology (that is, while two things happen that could not normally logically coexist), the fact that there are two worlds resolves the contradiction by placing those two realities that couldn't coexist in separate realities.

The fact that it's a little out there and fantastical (well, maybe it's not outside of reality, but outside of experienceable reality) makes it cool and interesting, but the fact that it's an obvious plot device and that it's a bit of used-up plot device makes it a bit lame when you actually think about it
