In those experiments, the speaking portion of Joe has no clue what the other side is experiencing. Like they show it to him on the wrong side and say “can you see this?” “No”. Then they ask him to draw it, and to his amazement he does. It’s not just being unable to vocalize certain thoughts - they’re not even there to vocalize at all to that part of the brain. But the other half is happily chugging away with that info
This video by CGP Grey goes into it a bit more, but split brain patients have even had their two halves disagree. For example the conscious hand picking out something to wear then the other hand batting it away and picking something else. It’s quite fascinating to read about.
A disconnect doesn’t necessarily imply two separate conscious entities though, right?
