I would not be surprised if their thinking is something along the line of justifying some luxuries. For example, when my gambling bankroll is very large, I might think to myself - if I make another $500, I am going to buy a laptop - but not unless I make that $500. Leno or Shaq might be thinking... I am going to buy my niece a new car, but not off my regular income. This commercial is going to finance some gifts. I m well aware they can afford to buy as many cars as they want without "feeling" it... But that last time my roll was up around 17k... I remember buying luxuries down to 15k and then repeating the process for anything above 15k.
Who's to say for sure, but I know that's how I think when I am rolling
Side note - I usually degen my roll before i get to that luxury point !
