Also, while your opponent will know what order you did it, there's little reason to expect them to remember the circumstances when you Foretell a dozen cards.
Per the mechanics article
"In exile, you must keep your foretold cards clear. Your opponents won't know what the cards are, but they'll know which card you foretold first, second, and so forth. At the end of the game, if you still have any foretold cards in exile, reveal them to all players so they know the future you foretold was an honest one."
If your opponent shuffles foretell cards around they are breaking the rules. In an official game in what order cards were foretold has to be kept track.
