You mean the initial labeling happens (without loss of generality) such that the baby has always chosen A? That's not the swapping I was discussing.

I meant this bit:

> After the baby is shown the first two toys, they are placed under boxes and secretly swapped. Despite originally having chosen B, the baby instead gets to interact with A.

If the baby actually tracks the swapping (probably unlikely), then I think it's not the case that they "originally [chose] B" - unless (quite possible) I am misunderstanding something, which is why I seek clarification.
