For instance, when she is with Norrington and asks, "Know what? Which side you chose?" and later, when he kisses her.

Answer: He agreed to do a job in exchange for eternal life, with a few limitations. If he refused to do that job he'd be cursed until he fulfilled his duties, but that doesn't excuse him from the details of the previous enchantment. He didn't simply choose not to walk on land, he couldn't.
