The URL in the config has to exist and will be used for updating. So the config value is not about overriding anything, but is required information. The URL should not depend on the current revision you have checked out at the moment; otherwise, if the default URL in .gitmodules changed at some point in the history, and you check out some earlier commit in the superproject, the update of the submodule would not work: the submodule project still resides on the new URL, regardless of the old information in .gitmodules at the time of the old commit.
