This is not a realistic representation of guitar string motion. The kinks are due to the "rolling shutter" effect of the camera sensor.

"Rolling shutter" is explained here:

Guitar strings photographed with a rolling shutter are compared to the realistic representation with a global shutter here:

And that is only a representation, because guitar strings actually move in trapizoidal kind of motion. They express a counter motion at the opposite end of the string from where it is plucked. In other words they don't vibrate symmetrically from the center point of the string.

The full excursion of the string looks like a kind of moving trapazoid shape, but most of the excursion is expressed in the middle of the string. But where you pluck it, on the opposite end of the string, there will be a slight expression of that displacement as a reflection in movement.

Probably not a clear way to explain it, but that the best I can do. This explains it better with a diagram:
