Haha, yes. I interpreted the `and` in that sentence as the logical connective, and (A → B) says nothing about (¬A ∧ ¬B). But he meant `and` in the human language sense.

Given the ambiguous wording, I wouldn't expect anyone to answer confidently, and lost of intelligent people would answer eight rather than "they're equal."
