I don't know if this is a bug or is that ganja i smoke dstarting to kick in (just kidding) ..

If you look at those two pictures i attached, and look at the lists i circled you'll notce that the usernames positions on the list change, the first page i opened and then i went to check my tmobile.com phone satus and opened AO on that browser window again and when i switched back to the first one i noticed the usernames changing. The time difference between those two windows being open may be around 2 minutes max....
