My guess is it's simply one of those "we wanna insure that no one's so stupid they'll believe/do THIS" tactics, not unlike cutting out ticket or contestant plugs. Here, they are reinforcing that [whatever show] is NOT coming up next.
The fee plugs have disappeared from many newer prints of Buzzr shows. A while back they did ask how we'd accept credit crunches, and that went over as well as you'd think. So I guess they needed more ad time, and thus here we are now.
