Moderator flags as inappropriate should hide post

Hi! Continuing on this discussion and trying to clarify what is intended behaviour here. We have moderators on our forum that have been using the flag to alert each other of an inappropriate post. After three moderators have all flagged that post it is hidden. This has worked very well for them. After updating Discourse this is no longer possible as a post gets hidden as soon as someone flags it. Has this been changed or are they using the function wrongly? It’s a good way of working for our moderators. Do we have to change our process or can this be accomplished with the current version of Discourse? We’re still on 2.2.0beta4. Thanx!
