House Trained?

Apparently, we have house-trained Banks - not potty trained! This morning while running around the house in the buff with two parents urging him to use the potty, the culprit ran onto the porch. Well, we didn't think much of it except that he was naked and we weren't sure how the neighbors would like that. A few minutes passed and Banks came back in and announced that he has "poopoo'd". And, sure enough, he was telling the truth. He popped right on our pea gravel patio. And then to top it off, he asked for a plastic bag so that he could clean it up just like we do Charlie!

Is this a step in the right direction? Can we count this as a success? Or should we all go to therapy because we have trained our little boy like a dog?
