Did CBS require the cards to be dealt differently,
At the minimum, I don't have the first clue how this would even be considered as a remotely possible explanation.
If I were going to speculate in a totally wild-assed fashion (and any attempt to answer this question would be just that, wild-assed speculation), I would say that they probably did it this way because of Eubanks, and here's my totally-out-of-left-field logic for that:
Remembering what I do of him on that show, he was always very polite to his dealers, generally thanking them whenever they handed him something or did something for him or whatever. It would not surprise me if they did it the Perry way in run-throughs (remember those? Run-throughs?), and Eubanks broke up his rattle to thank the dealer when they handed him the first card, and it was decided it flowed better if they just dealt the card from the outset so he could issue the player their $200 and flow seamlessly into the game.
Of course, the Money Cards I found through a quick YouTube search totally contradicts this when the dude changes the card, but I'm gonna link it anyhow simply because it's such a freakin' good one:
