D-1 final game/over the backboard

[zanzibar]

I know that the ball is oob if it passes over the backboard from either direction. Thought I read somewhere that the ball had to pass "directly" over the backboard. I'm having trouble interpreting what directly means.
Situation 1
In NCAA D-1 final game an Illinois missed fg attempt during the closing minutes appeared to hit the rim and bound over the left corner of the backboard and travel about 2 feet from the left edge of the board.I think the ball even rolled on the top of the board for a while. There was no call. The camera did not follow the ball completely
so it was hard to judge the path of the ball. Let's pretend that it did happen as described. Is this oob?
Situation 2
Similar situation. A1 is 2 inches from the baseline and 10 feet from the rim and shoots the ball over the corner of the backboard. Legal or not?
