So, if your name was Mr Desperately Grasps-Atstraws, but it was addressed somewhat unconventionally as Mr [surname:] Atstraws, [Forname(s):] Desperately Grasps?
In other words it has your complete and reasonably unambiguous name, clearly intended for you (even without knowing that it was for you due to having been stopped by the occifer and warned at the time that you might be prosecuted), and you want to know if the formatting of your name in this "letter" (which the thread title suggests might be a NIP - even though no NIP is required due to you having been warned at the time that you might be prosecuted) somehow gives you a get out of jail free card?
Whilst it is perhaps better to ask on the off-chance there there might somehow be a defence in there, than to miss a viable defence due to assuming that it's too far-fetched to even bother asking the question - I regret to inform you that there is no such thing as a Nobel Prize for Optimism.
