In the circumstances where a recovery order is made to return children in accordance with court orders, it makes sense, and is quite often the case, that said orders will be revoked and new orders to be made in their place. This would occur either on an interim or final basis, depending on the facts of the case.
Sure, I see the contradiction, that one parent would withhold children (despite court orders) because of a concern that the other parent wouldn't return them. In any case, where a parent contravenes an order and a recovery order is necessary, it would stand to reason that the existing orders are not practical or effective and need a re-evaluation of the matter, whether or not that means continuing contact with the contravening parent or not.
Situations like these warrant a consultation with a lawyer to fully understand the circumstances of the case. Being a lawyer myself, I can only provide limited information as a response to your question, but I hope it helps none the less.
