The point that I was eluding alluding to personally is similar but not quite the same as this: one-handed trilling is an even motion (one finger/other finger/one finger/other finger) that can be done very consistently -- players have differing striking points, pressures, and heights (above the keys before striking), but in the end, each player does their motion the same way for a given speed. If the speed goes up, the motion is modified slightly (differing hand placement/pressure) but is still executed the same by string with one finger, than the other, and whatnot.

Vibrating is simply a release of tension; the recoil from a key strike will change a number of times, and the location/pressure of the strike will vary wildly. I also say this with some vibrating capability, as my right hand can vibrate around 190-200 BPM.
