Custom status duplicating

I'm not sure if anyone else experiences this 'bug'? but, I've noticed one person may have a custom status set, and then in my friends list another person has the exact same status set for about 10-20 seconds and it disappears... For me it seems to be the same 2 people, whether this is an actual bug, or maybe a catfish (lol)... I'd love to know if anyone else see's it happen.
