Regarding the seals: In "real life" they are useless to Erika if she cannot check them in a timely fashion. If she returns to the guesthouse 5 hours after the Logic Error resolves (assume the game goes on) and the seals on both rooms are broken, all she knows is that somebody left those rooms at some point. And if she never goes back, the seals are of no practical use.
This is not true of Dlanor's guarantees on the seals, which can clearly update Meta-Erika even when Piece-Erika is nowhere near the seals to check when they were broken or whether they're still intact.
Also recall that if somebody seals the room you are in from outside, you don't have any way of knowing the room is sealed until you break the seal.
If it were me I'd have tried to trick her by having a seal broken but not having anyone left.
