I'm going with the assumption that this is true (one full eviction rather than fake double eviction).
Endemol/C4 have seriously c**ked this one up - scrapping the secret room idea because Kitten broke the rules is ridiculous because it's only doing exactly what Kitten herself said they would.
They could quite easily have kept the secret room idea to fit in with their issued punishment - remove two housemates tonight in the planned way and simply say that one removal is the normal Friday eviction and the other is the result of rule-breaking.
Their plans needn't have changed, and it would have maximum impact on the rest of the housemates when they realised that Kitten was wrong, and BB meant it when they said that somebody would be removed for Kitten's rule-breaking. Cue lots of heated arguments, simmering resentments, and alcohol fuelled rants about the injustice of it all. Delicously evil. Not to mention the fun of watching two housemates spying on the others and coming back to the house full of revenge...........
Now, instead, we get Kitten ranting on about how she was right, and BB would have removed someone on Friday anyway so it proves it wasn't her fault, and nothing really changes - except that we might lose an interesting HM.
Nice one C4!
