Eyrie, glad you picked up on that... it's kind of like the idea that "kyusho jitsu" is taught today as "pressure points". When I started, "kyusho jitsu" meant "methods of hitting the body". It included pressure points, vital points, and yes... the ever-popular Dim Mak training to hit those "places that don't exist".
I have an Aikido student who gets a 1-hour "specialty" lesson from me on Wednesdays before Aikido class. I told him we would cover a couple of pressure points "to be used to effect movement" in case his Ki went on strike during an attack.

I got an "OH $***" every time I touched him when I taught him my brand of kyusho...

I didn't effect any knockouts, but he felt "encouraged to follow my lead"

when I executed the techniques, with one of the Aikido black belts sitting on the sidelines doing a belly-laugh all the way through the class.
She laughed at him and at the end of class told him "you ought to know better than to let Dr. Pain give you a treatment"...

(She's a physical therapist).
"Understanding comes depending on which end of the punch you happen to be standing on"...

... shame on me...
