The test was undoubtedly planned to demonstrate 150% of some Max ZFW limit. As it happens, it failed a few percent shy of that value.
Another way of stating this is that Airbus have demonstrated 150% of some lower ZFW value (~3 to 5% reduction). Assuming all other tests are met, the initial aircraft could be delivered with a reduced ZFW. This would imply some financial penalty for Airbus because of the reduced profit potential for the airline.
