Bruce Banner needs to focus his mind to control the transformation. Whether that's making it happen at will or keeping it at bay it's him using his willpower to control it. So it makes perfect sense that you'd need to focus to control it and whether that means you're bringing it on or keeping it at bay is incidental.

Now, I'm not a comic book person, but I was under the impression that what made Bruce Banner shift was his anger, and he's always angry. Thus he would have to control his anger to not shift, but as soon as he stops focussing on not being angry, he shifts.
