SpaceX only has one launcher at present, the difference between re-use and expendable use is a matter of how that hardware is used, not how it's built. Every Falcon 9 v1.1 launch to date has made use of the same, fundamentally reusable first stage core. To actually reuse the core requires bolting on some additional hardware (which has flown on 2 flights already) such as landing legs and then flying the stage back to land. In software terms this is like hiding new functionality behind a "feature flag" so that you can let the code bake in production for a while.
