IRI Finals Question

[JB987]

Watching the archive videos peaked my interest. Tons of great matches and kudos to all the competitors and champions. Can somebody explain to me how the human player hard bounce off of 2056 that returned to the in bounder was construed as an actual possession/assist...throughout the event? No intent to be argumentative, just trying to understand why such interaction wasn't called as an assist throughout the regular season events I attended or watched. Sure would have made things easier
