No, they're saying that the problems have been reviewed / play-tested by ≥2 humans, so they are not considered unfair or too ambiguous to solve in two attempts (a critique of some Arc-AGI-1 puzzles that o3 missed). They have a lot of puzzles so they were divided among some number of testers, but I don't think every tester had to try every problem.
