until 跟 as long as

The sale of government surplus machinery will begin at 9 am and continue until the supply lasts.

The sale of government surplus machinery will begin at 9 am and continue as long as the supply lasts.

为什么第二句比第一句好？ 是因为continue只能与as long as 搭配， 还是因为 as long as 与 the supply lasts 在逻辑上更为合理？谢谢各位能人！

句子的意思，第一句说要在9点开始并继续直到供应持续，逻辑不对，第二句说会继续只要供应持续
