If you took one world and extrapolated backward, you'd get many pasts. If you take the many worlds and extrapolate backward, all but one of the resulting pasts will cancel out!

I agree. However, at the same time, we don't actually remember the many extrapolated pasts of the one world we inhabit. Of course, "remembering" multiple extrapolated pasts might be indistinguishable from failing to remember any particular past (e.g., if both X and not-X lie in our extrapolated past, then our "remembering" both X and not-X might be nothing other than failing to remember whether X or not-X).
