Because they were never in one lift long enough. Yes, Hubbell was lifted for > 5 seconds, but it was split between two different lifts. If Donohue was stationary for 5 seconds, it would have qualified them for a Level 1 Stationary, but he was not. Once he had directional momentum, that with the rotations created a rotational lift, which has different rules governing levels than the other lifts. Because the panel classified the lift as Stationary, only the parts where Donohue was stationary counted toward the "Lift" segment features. Everything else was considered as part of the entry and exit features, which essentially don't apply if a team doesn't have any "Lift" segment features.
