True, but not the reason for this seemingly paradoxical turning situation.

Actually, that is EXACTLY what it is! It's called 'counter-steering' and it's the most accurate way to control a two-wheeled single-track vehicle. It only takes fingertip pressure to handle high-speed maneuvers.
So, Sneaky, you're up! And if you want the full answer, well,
OK... ready? (From the Net)
The technique used by motorcyclists to initiate turning in a given direction is to first apply a steering torque in the opposite direction. For example, if a turn to the left is desired, it is started by a turn of the handlebars to the right. Under this force the front wheel will rotate to turn right and the front tire will generate forces to the right. The machine as a whole steers to the right briefly and the rear tire also generates forces to the right. Because the forces are applied at ground level, this pulls the wheels "out from under" the motorcycle and to its right. The resulting roll angle to the left causes the tires to then generate camber thrust to the left providing the centripetal forces required to turn left. The geometry of the steering system provides the forces necessary for the front wheel to adopt an angle turned into the turn in a conventional manner. It is often boiled down to "push left to go left".
While this appears to be a complex sequence of motions, it is in fact known unconsciously by every child who rides a bicycle. The entire sequence goes largely unnoticed by most riders, which is why some assert that they don't do it.
It is often claimed that two-wheeled vehicles can be steered using only weight shifts. While this is true for small "trim" inputs to direction, complex maneuvers are not possible using weightshifting alone because even for a light machine there is insufficient control authority. Although on a sufficiently light bike (especially a bicycle), the rider can initiate a lean and turn by shifting body weight, there is no evidence that complex maneuvers can be performed by bodyweight alone.
