Looking for a rulebook interpretation on a FT

[smokeybandit]

Here's the rule snippet:

RULE 9
Section 1. Free Throw
-Art. 2. After the ball is placed at the disposal of a free-thrower:
e. No player shall enter or leave a marked lane space..

--------

What does "disposal" really mean? When the ref tosses the ball to the shooter? Or when the shooter has possession of the ball?

In the Penn State/Minnesota game last night, Penn State (shooting team) was called for a lane violation when the rebounder (at the coach's request) left the lane, just as the referee began to toss the ball to the shooter. Player was called for the violation because of it.
