I think you might be misinterpreting that. I always understood it to mean that when the two hemispheres can't communicate, they'll make things up about their unknowable motivations to basically keep consciousness in a sane state (avoiding a kernel panic?). I don't think it's clear that this happens when both hemispheres are able to communicate properly. At least, I don't think you can imply that this special case is applicable all the time.
We have no reason to believe it is a special case. The fact that these patients largely functioned normally when you did not create a situation preventing the hemispheres from synchronising suggests otherwise to me. There's no reason to think the ability to just make things up and treat it as if it is truthful recollection would just disappear because there are two halves that can lie instead of just one.
