First, from what I can see in the vine it looks like Hochuli said "The difference is you were running" which is exactly what he told Blandino. What we don't know is if anything was exchanged before that. I have a feeling when Cam was still on the ground and Hochuli was facing the sideline he said something to the effect of 'You aren't old enough to get that call' which may have prompted Cam to ask him to repeat himself, like a 'Wait, what?' and then the part caught on tape is Hochuli clarifying the no call by saying he was running.
