I don't understand the doctrinal changes you cite (“Judging” effective 1995) Can you clarify that?
This refers to a doctrinal change in 1995. Most know that "the generation" change was made then. But the Society also changed the way they understand the judging of the sheep and goats. Previously the Society taught that Jesus was judging and separating the sheep from the goats since 1914. Then in 1995:
*** w95 10/15 p. 22 pars. 22-25 How Will You Stand Before the Judgment Seat? ***
Does this parable apply when Jesus sat down in kingly power in 1914, as we have long understood? Well, Matthew 25:34 does speak of him as King, so the parable logically finds application since Jesus became King in 1914. But what judging did he do soon thereafter? It was not a judging of "all the nations." Rather, he turned his attention to those claiming to make up "the house of God." (1 Peter 4:17) In line with Malachi 3:1-3, Jesus, as Jehovah’s messenger, judicially inspected the anointed Christians remaining on earth. It was also time for judicial sentence on Christendom, who falsely claimed to be "the house of God." (Revelation 17:1, 2; 18:4-8) Yet nothing indicates that at that time, or for that matter since, Jesus sat to judge people of all the nations finally as sheep or goats.
If we analyze Jesus’ activity in the parable, we observe him finally judging all the nations.
The parable does not show that such judging would continue over an extended period of many years, as if every person dying during these past decades were judged worthy of everlasting death or everlasting life. It seems that the majority who have died in recent decades have gone to mankind’s common grave. (Revelation 6:8; 20:13) The parable, though, depicts the time when Jesus judges the people of "all the nations" who are then alive and facing the execution of his judicial sentence.
In other words, the parable points to the future when the Son of man will come in his glory. He will sit down to judge people then living. His judgment will be based on what they have manifested themselves to be. At that time "the distinction between a righteous one and a wicked one" will have been clearly established. (Malachi 3:18) The actual pronouncing and executing of judgment will be carried out in a limited time. Jesus will render just decisions based on what has become evident about individuals.—See also 2 Corinthians 5:10.
This means, then, that Jesus’ ‘sitting down on his glorious throne’ for judgment, mentioned at Matthew 25:31, applies to the future point when this powerful King will sit down to pronounce and execute judgment on the nations. Yes, the judgment scene that involves Jesus at Matthew 25:31-33, 46 is comparable to the scene in Daniel chapter 7, where the reigning King, the Ancient of Days, sat down to carry out his role as Judge.
