Nonsense.
In 1972, they introduced different pricing games in a modified format. But the original format was itself a pricing game, and it wasn't the only one either. They routinely played different pricing games for special prizes. They may not have had special names for them, and they didn't even play them every show. That's why the seller correctly referred to the 1972 version as a "modified format".
If you want to go fishing for mistakes, go to sentence two and see that there's no reference to the Cullen show moving to ABC for a while.
