That’s just a regular under rotation. He’s hardly the first skater to have his toe pick touch the ice with the boot facing a different direction than when the ball of the blade/rocker is touching the ice. If the tech specialist didn’t call that, it’s a miss. But to say he’s deliberately doing it makes no sense. A skater wouldn’t ever train their jumps to be ambiguous on the landing because it could go against them depending on the caller.
Think about what you’re suggesting from a physics standpoint.. Zhou has all this horizontal momentum/speed going into his jump, takes off with an arc trajectory on his jump (ie not straight up and down), and according to you is somehow able to completely stop any momentum he has at the exact moment of landing, turn on his toepick to complete the rotation and avoid leaving a hook, and then magically regain all that momentum to exit on a flowing backward outside edge.
Think about it - can a ballerina do a horizontal leap, with distance, and land right on their toe and immediate do a pirouette? No because their forward momentum from the leap would prevent them from staying in the same spot upon the landing. However a ballerina at a stand still could conceivably jump straight up, start spinning, land en pointe and continue to pirouette in the same spot from which they took off - because they have no horizontal momentum to force them off their toe.
For Zhou to land and turn on his pick in the same spot (like a male pairs skater’s pivot foot in a death spiral), he would literally have to perform the jump precisely just up and down, with only height and (mathematically speaking) zero distance, so that upon landing he could turn on his pick - because any horizontal momentum maintained throughout the jump would invariably result in a hook on the ice because his momentum is still going in a horizontal direction.
