The emoji id for a wallet should not change when a restore is done. If the seed words are removed, then the restored wallet will have a different emoji id.
I suggest storing the secret key for the emoji id in stage 1b, or at least mentioning that it should be explicitly removed
Correct. To avoid leaking all future funds, the trade-off is that you import the old UTXOs into a new wallet. You're not really restoring the wallet per sė. We should update the text to make this clear.
