Obviously what you see very much depends on the position of the camera.
Care to clarify?

Yes, I'll clarify. Except for a most extreme position, the position of the camera doesn't really matter....if you see it through the glass, it can only come over the top. The only position that that could yield different conclusion would be a position such that the line of sight is almost parallel to the board....looking along a line between the basket and the ring..and then reflections would likely prevent you from seening through the board anyway. Any camera angle more than a few degress in front of the backboard works. The camera angle they showed was from approximately the C position...but elevated.
The converse is NOT true, however. You can't say that it didn't go over the board if you don't see it through the glass...in that case there are several camera angles (e.g. orthogonal to the path of the ball) that don't tell you anything. In this case, camera angle from the same side of the floor as the shooter wouldn't be useful...either positively or negatively.
To describe the geometry of the objects another way...if at the time the ball is level with the basket there is any part of the backboard between the any part of the ball and the center of basket (using diameters of 18" for the rim and 9" for the ball), the ball can't get directly into the basket without at least part of the ball going over the backboard. If you consider the possibility a front-iron bounce, you could conceivably get approximately a little more room...about 3-4" at the theoretical limit.
Now, considering that the framing/padding of the backboard obcures the first 2-3" of visibility through the edge, whatever you see is already beyond that which could be used in a front-iron shot....So, if you see it through the board...it can only get the the basket by going over the top.
