I personally do not think that the neutral tag is worth it. I read your post in his self moderated thread, it was very much on topic and doesn't deserve to be deleted. My own post was also deleted by him but I took it in a good fate.
If you are going to post in a self moderated thread, be willing to accept harsh moderation
Harsh moderation from a poster that is not reputed. But good moderation from a reputed poster. I think that is how it could be. If such topic was posted by a newbie, I would not have posted if it is self-moderated. Many of us might not have posted. Also the neutral tag is harmless. Just a warning to let people know that their post could likely be deleted. I wanted not to give the neutral tag but almost all posts are getting deleted. I will remove the neutral tag after a week when everyone would have seen it.
