[1.2.384] A Cannon Shooter is born

Rig, I saw in a video in the cinema thread where a Cannon shooter was being propelled by the skills sometimes. Are there times when you can be launched forward or backward when using certain skills, or was the person just lagging, or does getting hit in the middle of the skill knock you back that far?(It's in the 4th job video in the ''Cannon shooter video's'' thread.
