Thanks for posting this, I know exactly what you mean. Segovia is famous for promoting nails into classical guitar playing, and, along with them, a more direct way of plucking, which results, it's true, in less effort and movement of the hand over all, because all motion is carried by the upper side of the fingers. I don't have nails, though, or at least not the amount needed for this time of plucking, so what I do is plucking with a combination of flesh from the top of my fingers and a bit of nail. I would say 70% flesh, 30% nails. This specific type of plucking requires a different movement, I'm almost pressing the strings to the inside of the guitar.

Here's a very detailed video explaining the differences:
