I dont own a trezor but this kind of fill up form is literally an obvious scam. What the hell, why the user need to confirm its phrase so the data will not be corrupted and damage. Pretty lame to fall with the likes of this scheme.
Very easy trap for newbies, maybe even for intermediate users.
Most wallets require you to rewrite the seed after saving it in order to make sure it's the correct one. It's easy to mistake that assurance step for this one.
