Spot Throw-in Question

[medlin]

Ok, I looked up the rules last night in both rulebooks.
Here's what they say. For those of you with books handy, I've referenced the rules below:
NCAA: Rule 9-2.4 Art. 1 says that the thrower-in shall not
a.) Leave a designated spot.
Definition of a designated spot: Rule 4-15 A
designated spot shall be 3 feet wide with no depth
limitaion.
The NFHS Rule Book essentially reads the same (Rule 7-6 Art.2) as the NCAA rule. The definition of the designated throw-in spot has a note included. Rule 4-41 Art. 6 NOTE: "The thrower must keep one foot on or over the spot until the ball is released. Pivot-foot restrictions and the traveling rule are not in effect for a throw-in."

I know that the traveling siganl was wrong (and therefore confuses the aveage fan, coach, and announcer.) So, I guess the question is, since the NCAA Rulebook doesn't have the 'NOTE', does the thrower-in have to keep both feet in the box? (There aren't any mentions in the handy 'rule differences' charts in that can be found in the back of the NFHS Rules book or the CCA Officiating Manual.)
