What does it mean when I guy says "Till the next time our paths cross"?

We met and had a 3 day fling, we connected and talked about meeting in the future. He lives very far away (Australia) and it has been almost a week and have not heard back after he texted "Till next time..' which I replied with I had a feeling we would meet. I just came back today from the destination where we met and wonder if this will continue?
