Samaritan threat

So in root path after decima gets the chip, machine analyze death probability of all the characters because of samaritan, that had finch , john, shaw , Fusco, Collier ect. But unless I missed I don't think there was anything about root

Was it because there was chance that Samaritan might try to recruit her instead of directly eliminating her, Greer does offer her to join them in next episode, or was there some other reasons?
