ReadRemoteConfig is the same with WatchRemoteConfig ?

After reading the source code, I found that viper.ReadRemoteConfig is the same with viper.WatchRemoteConfig.

viper.ReadRemoteConfig invokes RemoteConfig.Get, in remote/remote.go

func (rc remoteConfigProvider) Get(rp viper.RemoteProvider) (io.Reader, error) {
    cm, err := getConfigManager(rp)
    if err != nil {
        return nil, err
    }
    b, err := cm.Get(rp.Path())
    if err != nil {
        return nil, err
    }
    return bytes.NewReader(b), nil
}

viper.WatchRemoteConfig invokes RemoteConfig.Watch, in remote/remote.go

func (rc remoteConfigProvider) Watch(rp viper.RemoteProvider) (io.Reader, error) {
    cm, err := getConfigManager(rp)
    if err != nil {
        return nil, err
    }
    resp, err := cm.Get(rp.Path())
    if err != nil {
        return nil, err
    }

    return bytes.NewReader(resp), nil
}

Obviously, they are exactly the same. What's the purpose？
