no i think he literally means just dropping the bar to your chest and pressing it back up explosively and pin presses
ive seen people do it and some people can do it fine. ive done it myself and i got extreme elbow and shoulder pain. pin presses are hard on the joints as well and as i said some people do it fine, i get fucked up eblows.
eccentric portion of the lift is important too, i think it is important not to neglect it.
