NFHS Signals

[Freddy]

I've always been taught that the hand mechanics for calling a violation are: 5,4,2, that is, open upraised five-fingered hand, the violation signal, direction of the ensuing OOB throw-in with four fingers, then spot of the designated throw-in with two fingers. The old 5-4-2.
While prepping for a small-group pre-season rules meeting on NFHS signals, I now note that the faceless picto-guy in the back of the book shows 5 for the direction signal (pic 6) and only 1 for the spot of the throw-in (pic 26).
Is this new, or have I been taught incorrectly all these years?
Any insights on this issue of the NFHS authorized signals?
