It was already mentioned that the third Ootsutsuki was initially designed for Boruto movie as the third villain along with Momo/Kin, but got screwed up in the process. Oh, i think he only exists as in "he is canon". Considering how Boruto achieved his mark, how Kawaki has a similar mark and how the guy didn't show up in the movie, odds are that he's dead, very dead.

But considering that anime episode aired well after the movie, they knew Kishimoto's decision et all, i find it hard to believe they just accidentally added that guy.
