I believe it was a "double up" feature that could be envoked after the hand was dealt - similar to doubling down after you see your hit card.

In my experience all VP 'double up' features are envoked after you've played you hand. Online the standard is that if you win (or push) any amount on the VP hand, you are offered the option to double up. This is a seperate game, where the funds that should have been paid on the VP hand are wagered on a 50/50 shot usually involving a high card/low card senirio. So all double up play would take place after the hand was dealt.
From what i can pick out, these guys had gained access to one of the settings menus behind the game. They'd play for a tiny coin size, say 5c, then when they hit a winning hand they'd go into the hidden menu and bump the coin size up to the maximum. So when they lose their losing pennies and when they win, they win like they were using a $5 coin size (or possibly more).
I don't think this falls into a casino error catagory. While it was a glitch in the game it's not like a payout error - they were accessing a settings menu and altering the value of their bet. I think this falls a lot closer to chip switching - betting a couple of $25 chips on and hand and switching in a $25 capping a $500 when you win. They were knowingly altering the game to receive a payout for a higher coin size than they played and as such i really doubt any fallout from this case elsewhere.
