This is from the link you provided:
“By starting the verification process, you are telling the device that you want to run the recovery process, but you do not want the device to remember the seed. Instead, in the end, the device compares the seed saved in its storage and the seed you have just “recovered,” and the result of this comparison is sent to the Wallet interface.”
My interpretation of the above is that whatever seed you enter, right or wrong, during the verification process nothing gets written to Trezor; all the dry-recovery does is, check the seed that you enter with the seed that is already in the Trezor’s storage. Irrespective of whatever seed you enter, right or wrong, during the verification process the seed that is already stored in Trezor should still remain intact and unchanged at the end of the verification process. However, I have to stress that the above is just my interpretation and I have never tried and tested the dry-recovery process before.
