From the original pics, it can be seen that some of the roots have roots branching out from the main roots. So ----- as long as a root stays alive, it could possibly send out branches. And new roots can grow from the rhizome etc. The main thing is to keep the orchid nicely hydrated ----- its bulbs and leaves, and to keep existing roots alive. And this orchid will definitely make it.
