No way. The skier that hit the jump was also clearly at fault here along with the spotter. I see this happen all the time with people going for jumps or rails, who obviously know better, should stop but don't. If its not clear, or has the potential to not be clear then you don't hit the feature. And as a spotter you don't give the all clear till it is all clear.
There was a 50/50 chance that girl was going to cut under the jump, hell I'd even say more then that just from experience of watching inexperienced people run through the park. She was downhill to the skier and he hit the jump anyway.
