I am sure the quarantine to network share will work properly. Since the files are not on the local machine after quarantine, I doubt the recovery will work as expected.
I tried the quarantine to network location feature today and it worked.
While the files are indeed moved to central network location, the "Release from Quarantine" feature does not work as expected. It will not restore the quarantined file to the endpoint from which it was picked up, instead it will simply restore the quarantiend file to a similar directory path from whichever endpoint the 'Release From Quarantine' action is fired.
