Provided that the recorded information has not interacted with anything in the preceding 10 year, such as you looking at it, then when it is erased there is no longer any difference between the 2 universes and thus they recombine. And so if you then develop the photographic plate a interference pattern will be observed on it. If you didn't erase the information they wouldn't recombine and thus no interference pattern would be found when you developed it.
