The discussion of the artwork and what qualifies as a crucifix aside, I think the original post might be a bit mistaken in the assumptions.
That video was made over 3 years ago, it shows the old seminary, not the new seminary and thus the old conference room in the basement under the chapel (the former bowling alley).
The crucifix/cross/artwork was there since at least 2007 when I remember attending an adult Catechism there on a Sunday. I was told it was a gift of one of the seminary priests to the seminary when the room was converted from the bowling alley into the conference room, so it probably was there earlier than 2007.
I have seen dozens of similar pieces of art in old churches, especially neo-Gothic, Jugendstil-style or Beuronese-style churches, showing Christ the King as High Priest nailed to the Cross in vestments. They were especially common in the early 20th century, particularly the 1930s. Almost every single one, except the more modern ones you can find today, have Our Lord wearing a maniple, so certainly not a post-Vatican II phenomenon.
I'll leave the definition of what qualifies as a crucifix and what is tasteful art to others, but the history of that piece of artwork of that seems important to point out. It's not at the new seminary, as far as I remember on a tour of it, and at the old seminary it was in that room for at least 10 years before the video was made, so isn't something new.
