What don't you understand dragon man?
If you are on LWOP you are employed by the company. If you receive CR you are not. You have nothing to do with the company whatsoever. You keep your name on a list and that's it - hopefully one day you will get the call.
The question you are getting at was specifically asked in a webinar and the answer was as I mentioned above.
If you refused to come back from LWOP early and they were short of crew, then they will recruit externally (i.e. call back the CR pilot).
It's not rocket science mate. Jesus!
