I'm not 100% sure what you're asking, but I do think they know when their diapers are wet or dry, and I do think they care. My son tries very hard not to go in his diaper, and once it is wet, he doesn't want it on him. I think one of the goals of EC, beyond keeping them dry, is to help them learn the connection between peeing and having a wet diaper, but if they go back into a wet diaper after they've pottied, they're missing the chance to get that pee/wet connection reinforced every time, and they're missing the reward of having kept their diaper dry (the reward is comfort), and they're missing the chance to be in charge of the state of their own bottom.
