Gomme boxes bug minecraft?

I just discovered a bug in the GommeHD Chat.

First of all I wanted to draw attention to it and just ask how he does it?

You don't see it in the picture but the news all came in within a minute. Say he pressed something to get the item of his choice.

Maybe he was just lucky

Never xD that within 1 minute so often is impossible especially those were 2 accounts that were so lucky

It's safe some glitch if he won it in such a short time.
