The result, when done correctly, is that the aircraft is both pointing directly down the runway and travelling directly down the runway at the moment of touchdown. This is perfectly normal, and pilots are trained to do this. However, if there's an unexpected gust of wind just as one wheel touches down, or the pilot is clumsy, you can get the one-wheel bounce you describe.
