Huh? This doesn't make sense. The only way a flag like this can be disputed is by being reviewed by a 10k+ non-moderator. However, if that is the case, then why does it say that a moderator reviewed it?
Flags are dismissed as helpful or declined by a moderator; they are marked disputed if a community member disagrees with the flag. So in this particular case, not only did a moderator disagree with the flag, but one or more community members also disagreed with the flag.
