The point is: If you don't abuse your phone by dropping it on the ground, you know the warranty protects you. If you gently splash your phone, it's very possible it could break because it was defectively sealed, but the warranty won't help. Lots of products that are supposedly water resistant to X degree have not lived up to their labels. They should not be claiming any level of water resistance if they're going to categorically exclude water damage. It's one thing to say it is more likely to survive a splash than previous phones. But they're making a very specific claim that a certain amount of water is safe. That claim should have teeth.
