The particle "wa" is very important here. It makes sure you understand the condition. It shows a clear difference between when the condition is true and when it is not. Without "wa," the meaning changes. It could mean "to the fullest." With "wa," it only means "as long as."
This grammar is different from "~kara ni wa" and "~ijou wa". Those phrases show a reason for a strong decision. This grammar shows that two things happen at the same time. One thing stops, the other stops too.
Don't use this when something happens only once. For example, not for "as long as I ate breakfast."
