Interesting to know the South Canadian rule.
Here, a pass' direction is determined by the originating location and by the terminating location.
The originating location is that spot from where the ball is thrown. The terminating location is the Point of First Touching, or where the ball touches the ground, or where it goes out of bounds (in flight).
In Canada, this is a had to be there sitch. Sounds like it would have been a lateral in Canada, and therefore a live ball.
