Since IoT Hub does not support patch operations on arrays (if you want to update array, you need to replace it), they don't allow null values or null properties inside arrays. EdgeHub, on the other hand, allows that. So, validation can pass on the EdgeHub side, but the update will be rejected by the hub. This situation allows for sending bad payloads, that blocks any further twin updates unless bad property is removed/cleared.
