I doubt it was the same thing. I vaguely recall a scene like that, but I think it was the shock of recognition after being gone so many years.
I think the mistake (aside for, in GH's case, the secret itself) is in doing at a point when they were so frontburner. If you can fix on a point in the characters' onscreen lives where they were not, say, in frontburner A-story, then retconning new stuff into a past era is not a big deal IMO. This was not the case for the Webbers at that time. Same goes for, say, Viki and Jessica and the disgusting molestation retcon Higley wrote for Jess on OLTL - Viki, Clint and their family were frontburner almost nonstop during Jessica's childhood years in question. Even if the retcon were somehow acceptable, which it wasn't, it would not be possible.
