I think the deeper dynamic is that any time anyone experiences a red pill, it's akin to a higher energy state and they become extremely receptive to sliding right back down into a different blue pill paradigm. In fact it's natural to eagerly crave it, as turning the deductive-reasoning crank forwards yields a whole batch of new fresh "insights" without having to do much work to obtain them. In the context of the movie, imagine - shortly after Neo takes the red pill, acclimates to the real world (rough), starts his training, says "I know Kung Fu", and then refuses to leave the training sim because it is so damn stimulating in new ways he isn't used to.
