No, he doesn't know it's wrong. Dogs don't think that way. He's slinking off into a corner because he's reading your emotions and reacting to them. He doesn't associate it with what he did.
How old is this pup?
Not only do puppies pee and poop frequently, but it's also not unusual at all for puppies to need to pee and poop multiple times in one setting. Just because he does each once when he's outside doesn't mean he's done, and he may need more time outside before coming back in.
Is he on a strict feeding and potty schedule? That will help tremendously.
If he does have an accident indoors, make sure to use an enzymatic cleaner like Nature's Miracle or Simple Solution to thoroughly clean the area. Regular household cleaners may seem to remove it, but they leave residual scent behind. You may not be able to still smell pee/poop there, but dog's can. Dogs are very scent oriented when it comes to relieving themselves and if they smell that they've peed/pooped somewhere before they are more likely to return to that spot to do it again, and smelling it will also trigger a response to pee or poop. So you need to make sure any possible pee/poop smell is removed from the house so he can't smell it.
Dogs are creatures of habit. Everytime he potty's in the house he's learning that it's ok to potty in the house. Correcting him for doing so isn't the answer, as many dogs will simply learn that they shouldn't pee/poop in your presence, not that they shouldn't do it in the house. So they may just learn to sneak off to a corner where you can't see them to pee/poope, and they may become less likely to potty outside when you're with them because they fear corrections from doing it in your presence.
You need to be proactive and prevent him from doing it altogether, not just wait to correct him when he does. Make sure he's on a schedule and take him out frequently, making sure to give him plenty of time to pee or poop multiple times if he needs to. Never let him out of your sight when in the house. Use doors/babygates or a leash tied to your beltloop to keep him nearby at all times. And watch him. Any sniffing the ground or circling indicates he's getting ready to potty, so get him outside quick. And make sure to praise him lavishly everytime he potty's outside. When you can't keep one eye glued to the pup at all times, he should be in a crate where he can't get into trouble and where natural instinct will tell him not to pee or poop.
