How many points for dunking from the 3-point line?

[BillyMac]

5-2-1: A successful try, tap or thrown ball from the field by a player who
is located behind the team's own 19-foot, 9-inch arc counts three points. A ball
that touches the floor, a teammate inside the arc, an official, or any other goal
from the field counts two points for the team into whose basket the ball is thrown.

I'm trying to understand some posts. Some of you are saying that if the shooter touches the rim before releasing the ball, you consider him to be shooting from within the three point arc, and thus, it's only two points.

And, if the shooter touches the rim after releasing the ball, you consider him to be shooting from outside the three point arc, and thus, it's three points.
