Only time you take immediate action to cut an engine between V1 and 400' is thrust reverser unlocked with buffet/yaw.For this reason,I am sure the video is a hoax.Professional pilots arent trained like this.

I think the TOCW was disabled;just a question of why.Can you set the parking brake in the MD80 when airborne or arm the T.O position of the autobrakes on approach?
