Yes, but part of the article from the 1995 WT seems to be talking again through their two mouths because after point out the differences of the other sheep and the great crowd, come with this paragraph:
Understandably, though, for these to survive the approaching great tribulation, they must earlier have washed their robes in the blood of the Lamb, becoming true worshipers. Hence, though Revelation 7:9 is describing this crowd after the tribulation, we may apply the term "great crowd" to all with earthly hopes who are rendering Jehovah sacred service now, just before the great tribulation breaks out with the nations' attack on false religion.
