NFHS Traveling definition descrepancy

[hoopguy]

I was doing my summer reading of the "2008-2009 High School Basketball Rules Simplified and Illustrated" by the NFHS and came across a slight difference in the Traveling rule.

On page 43 of "Simplified and Illustrated"
"4-15-3 Legal method of starting a dribble. The ball leaves the hand before the pivot foot is lifted. The dribble may be started by pushing, throwing or batting the ball to the floor. A dribble is ball movement caused by a player in control."

I do not believe the portion in red is in the regular rule book. It is definitely not in 4-15-3. I am wondering if the portion in red was removed from the rule book at some point in the past.

Is the ball leaving the hand before the pivot foot is lifted is how the rule is normally applied? It seems like it is not called this way now. I may need to rething traveling violation if it should be called this way. The "Simplified and Illustrated" book is produced by NFHS so I am wondering why there is a difference in the definitions. I would think that the more precise definition would be in the regular rule book not the 'Simplified and Illustrated".
