But as far as I have read the article the glitch is not about the simulation of cards but rather about game mode flags you can carry unintendedly between different game modes. The quoted example makes him pause game one at a high win, switch to game type two to achieve a 'tenfold win' token and then combine this with the paused game. These are arbitrary rules put in place just for the simulated card games in the first place. And of course for him it hugely increases the probability to achieve this scenario intended to be very rare.
