He chose to become a Heartless, rather than having his heart forced away by another Heartless or by research. Because he willingly chose to be a Heartless, he retained much of his thoughts and desires. I think that is why he was able to plan, although of course, his plan was to capture more hearts, like any Heartless (he was just going after the biggest heart of all).
This is a sound theory. Here's a supporting argument. When Sora became a Heartless, he did so of his own free will. He became a Heartless, but he wasn't operating on pure instinct. I think that's what kept him from attacking Donald, Goofy, and Kairi, because he wasn't acting on instinct. Instinct would have prompted him to attack the group immediately. Does that make sense?
