It is basically to achieve a sharper foreground while preserving an acceptable sharpness for the faraway objects. Basically a compromise technique to maximize DOF. The 1/3 of the way rule of thumb is the same advice as using the hyperfocal distance. Just worded differently.

Every lens is geared differently and your subjects are at different distances with different aperture settings. I occasionally use macro lenses to shoot far away objects. Pulling the focus 1/3 of the way back would mean quite a blurry image most of the time, so its not a useful tip.

I'd suggest just understanding each of your lenses intimately and knowing where the hyperfocal is for most situations.
