I think he confused your last post being "2 days" old with 1 day, and thought it was under 24 hours. Infraction should be reversed, but I'm pretty sure that was the simple mistake.
Another thing, I'm pretty sure he won't abuse his powers like that. If you were insulting/flaming him then I'm pretty sure he just meant he'll report it to us, and you'll most likely get banned for it. If that was the case.
Anyway, @Liz infraction should be reversed.
