reaping the knee happens anytime you put pressure against the outside of the knee forcing the knee inward toward the centerline. in the straight footlock in the video, the guy would have been fine if he'd gone for the lock by putting the leg under him, against the mat. that way the pressure would have been on the inside of the knee pushing out. the knee works fine this way.
the mechanism of injury for a heelhook is this exact thing - you turn the foot at the heel to force the knee from outside to inside, and by trapping it with your legs it doesn't allow the joint to move where it needs to and so causes ligament damage.
the reason for the rule against reaping is NOT stupid. the knee often goes without any warning pain. often by the time it hurts, it's already destroyed - tapping is pointless. therefore, it's left to more experienced players (eg, advanced no gi) who are assumed to have the experience to recognize and accept the risks to be safe. yet still we see plenty of injuries from heelhooks in advanced divisions.
the reason the OP is bent is because reaping is never allowed in gi divisions, even at blackbelt level (see galvao tooling some jjj guy for this for reference) and i've never seen it allowed anywhere other than advanced nogi. reaping can occur in a buncha non-footlock scenarios as well, particularly sweeping from open guard, so refs need to be sharp to prevent injuries and DQs at lower experience levels. OP's complaint is totally legit, IMO.
