Those were changes they made quite a while back. It used to be if one person goes rogue (not rouge by the way which the name for reddish color in makeup), then the whole group instantly goes rogue.
Now, after the "rogue 2.0", if one person flags as rogue, the others have a short period of time in which to also go rogue, or they drop from the group. That is why you see the short delay.
