You didn't do this (shocker!).

What's there to explain? Read the page.
"To enter fast in a right-hand turn, the rider applies a quick torque on the handlebars to the left."
Wow! Counter steering!
It goes on to say:
"The movement of the front wheel around the steering head generated a front tire lateral force that has the effect of leaning the motorcycle to the right. The gyroscopic effect generated by the front wheel and the steering rotation also has an important effect on fast entering in a turn. This gyroscopic moment has the effect of leaning the motorcycle to the right. Once the motorcycle has begun to roll to the right the rider can slowly turn the handlebars to the right, and the motorcycle enters the turn."
This is self explanatory, but I posted the second page anyways. Notice in the first graph the steering angle briefly goes negative (left)? Look down at the third graph. Notice how, at the same time, the roll angle is positive (right)?
>With regard to the second vid as I already wrote you can swerve back and forth all you want and not turn at all, or you can just lean it into the turn - there is no magic to "unlock" some secret force.
Not magic, just physics. I'll explain it to you one last time.
You turn the handlebars left. This generates a gyroscopic moment around an axis perpendicular to both the steering head axis and the front wheel axis (rightwards roll).
At the same time, tire forces pull the tire to the left, steering the bike left. This again induces a roll moment, as the contact patch is below the bike's center of gravity.
These effects cause the bike to lean right. This lean (and rider input) causes the wheel to turn right for the same reasons as discussed earlier, and the turn is initiated.
