Generally we put V for U only in caps, so not really."V" there I can't help thinking it would also have had a "V" for the "U" at the end of the word and in vivus too.
Well, maybe. But at least apart from that typo it still seems to make some sense, unlike some other ones (like your "pastus ab sodes bilis" one...).On the other hand, assuming any kind of logic was at work may be a mistake.
