My eventual take loosely is that the guy was somewhat of a charlatan/double-minded from the start so, it's fine - it's still worth trying to free yourself of desire you can probably do something like that, and best to go on as if this guy never existed.
EDIT: seems like there's a lot more to the story, and I think the poster you're replying to is assuming only the worst possible interpretation: https://www.reddit.com/r/TheMindIlluminated/comments/kw6wbl/...
Also, apparently he now has terminal cancer, and likely has less than a year to live. He's staying with family, which makes the above posters comment about "he is now isolated, leaving his very-much-extant sensual longings starved.)" seem untrue and unnecessarily cruel.
