The point is that saying something happened before the Crisis (even if it is the Post-Crisis version of the Crisis) is nonsensical at best as we know that certain realties survived Crisis. Case in point is Batman: The Last Angel which despite coming out in 1994 was eventually assigned to Earth-Thirty-Two. This makes assigning flashback stories to Earth-One or New Earth iffy at best.
