That's pretty much the response I would have expected. Dragon Age is more or less a generic fantasy setting tailored by Bioware, which means that they pretty much can do whatever they want with it. Just consider how many campaigns are set in the primary DnD settings, how many stories there are, and what not. Now, also keep in mind that they're referring to a setting, and not necessarily a specific type of gameplay too.
What I expect with both Mass Effect and Dragon Age, is that when Bioware makes a game in a Sci-Fi setting, it'll be in the Mass Effect universe. Whenever Bioware makes a game in a fantasy setting, it'll be in the Dragon Age universe. They don't need to have the same storyline running through all of them, as they're both pretty generic (which doesn't translate into 'bad' - quite the opposite in this case) settings that could handle numerous different plots and gameplay styles.
