So many uninformed opinions being spouted off as fact. The 8 moved. Video after the fact proves that. The ref's insanely keen eye caught it. Much like the foul he called on Albin that couldn't been seen on video replay at slow mo, but noticeable at full spd.
A video replay was not required to prove the 8 moved. I'm betting that's why they didn't bother. The likelihood of the movement not being caused by the CB passing by was miniscule.
Unfortunate call, ref did nothing wrong. You want to pretend pool is a sport..? ...well this is what you get.
Enjoy
