Nit picking on a field goal question

[sj]

NCAA.....

SECTION 4. Field Goal
How Scored
ARTICLE 1. a. A field goal shall be scored for the kicking team if a drop
kick or place kick passes over the crossbar between the uprights of the
receiving team’s goal before it touches a player of the kicking team or the
ground. The kick shall be a scrimmage kick but may not be a free kick.

b. If a legal field goal attempt passes over the crossbar between the uprights and is dead beyond the end line or is blown back but does not return
over the crossbar and is dead anywhere, it shall score a field goal. The
crossbar and uprights are treated as a line, not a plane, in determining
forward progress of the ball.

NFHS.....

8-4-1. A field goal shall be scored as follows...

c. The kicked ball shall pass between the vertical uprights or the inside of the uprights extended and above the crossbar of the opponents goal.

The NFHS casebook 8.4.1A-b says... The field goal attempt (b) is clearly over the crossbar between the uprights. RULING: It is a legal field goal.


************************

My question is this. Are these two rules saying different things? Or do they both mean that the entire ball has to go past the crossbar or does just part of the ball have to be over the crossbar?

In another situation concerning avoiding safety's a team must get the entire ball out of the end zone. What principle is applied here? The entire ball or just part of the ball?

Picking nits I guess but it's one of those once in a lifetime plays that you still have to be ready for.
