While they may have congregation records info and send to the GB, declaring yourself anointed does not mean you are a "genuine" or "real" anointed in god's view. The WTS has no official way to cancel an anointed jw's self-proclaimed status even by df'ing them. The WTS/GB reasons that the Corinthian man that was df'd and reinstated did not revert to other sheep status when he was reinstated.
So only god knows, supposedly, and now Jesus. (2012 quote follows, extra WT so-called confirmation follows in rest of article)

14. Why can we conclude that from the first century onward, there must always have been some genuine anointed Christians on earth?
14 In a parable, Jesus indicated that from the first century onward, there would always be some genuine anointed Christians on the earth. He compared them to “wheat” growing among “weeds.” (Matt. 13:30) Of course, we cannot say for certain which individuals or groups belonged to the anointed wheat class, but we can confirm that there have always been some who have courageously defended God’s Word and exposed the church’s unscriptural teachings. Let us consider a few examples.

Questions From Readers
● Can an anointed Christian who is disfellowshiped later be reinstated and still have the heavenly hope?
Yes, that is possible. Of course, in each case Jehovah God is the one to determine whether he will extend forgiveness.
The fact that this is possible is borne out by what we read in the apostle Paul’s letters to the Corinthian congregation. He wrote to Christians who had been anointed by holy spirit and given the hope of heavenly life. Paul addressed them as “you who have been sanctified in union with Christ Jesus, called to be holy ones.”—1 Cor. 1:2; 15:49.
One of these anointed Christians began to practice fornication. When he evidently did not repent and stop his immorality, Paul directed the congregation to disfellowship him. (1 Cor. 5:1-5, 9-13) However, it seems that this disfellowshiped person thereafter did sincerely repent. He is understood to be the person whom Paul was referring to in his second letter when he advised the Corinthians to forgive and accept back the former sinner.—2 Cor. 2:6-11; 7:8-13.
When that man was reinstated into the congregation, what was his hope? Had he lost the heavenly calling, and had his hope now been changed to everlasting life on earth? No, for the earthly hope is not, as it were, a second-chance prospect. Abel, Enoch, Noah, Abraham and multitudes of other persons of outstanding faith had the hope of eternal life on earth, but this was not because they failed to measure up to the heavenly calling. They simply did not live in the time when the heavenly calling was in process according to Jehovah’s will. (Heb. 10:19, 20) Comparable faith and integrity are required of all who will gain everlasting life, whether in heaven or on a paradise earth. A Christian who is anointed with holy spirit and made a joint heir with Christ must prove faithful to that calling if he is to receive eternal life at all.—Rev. 2:10, 11; Phil. 3:8-14; Rom. 8:14-17.
