    Q1 = A, Q2 = C, Q3 = B is also consistent no?

      Yes! Thank you very much! It is equivalent to shifting the green points in the x-direction to x=1. My mistake.
      The solution to the puzzle at 1:09 is indeed not unique.
      Now the video itself becomes a meme that self-referential puzzles are hard (even to make).

      yeah, I got those two solutions: A, C, B; D, C, B;
      my process for solving was just to write out the situation in formal logic. here's what I got (with the restriction that a_n, b_n, c_n, and d_n are mutually exclusive):
      a₁⇒¬a₂∧¬a₃
      b₁⇒¬a₂∧¬a₃
      c₁⇒¬a₁∧a₂∧a₃
      d₁⇒¬a₁∧¬a₂∧¬a₃
      a₂⇒d₃
      b₂⇒c₃
      c₂⇒b₃
      d₂⇒a₃
      a₃⇒¬b₁∧¬b₂∧¬b₃
      b₃⇒¬b₁∧¬b₂
      c₃⇒b₁∧b₂
      d₃⇒b₁∧b₂∧b₃
      if you work it out, the first thing's you'll find are that a₁ and b₁ are impossible, and from that a₂, d₃, a₃, b₂, c₃ are impossible. That leaves only the two aforementioned solutions left.
