BlenderArtists moderator activity status?

Hi. I’ve noticed some UI differences for a while now and I’m curious enough to finally ask about it.
The moderators section in the about page seem to be routinely rotating, almost like moderators that are active get shifted to the left? Is this a daily, weekly or plain activity displays? Or even assigned moderator job activity displays?

It’s just a rendering error, there are no shifts.
