Does "...be in the semi-circle..." mean:
A) lane space player's foot may not break the plane of the free throw line until the ball strikes the ring or the backboard, similar to what applies to the shooter?
B) lane space player may not touch the floor inside the semi-circle (cf. "you are where you were til you get where you're going")?
C) free throw plane is broken by any part of the body stuck out over the free throw line?

I think it's gotta be A).

A or B. Either action, with regards to FTs puts the player in the restricted space.
