I have to agree that there does seem to be a possibility that S&S might be resurrected (though of course they technically would never have died in the first place) if the distortion in time is ironed out. I'm not sure how I'd feel about this intellectually, but most deaths in CLAMP are wrung for maximum emotional pathos by depicting them graphically and at length, which of course has not happened here. Also Yuuko said she hadn't met Sakura "yet." So I'm rating this somewhat less than total despair. Maybe even cautious hope.
