(I do see that graphic at the end of the post. I take it to be a One Up On You kind of thing. Maybe not.)
E-Bike; with throttle, you only need to push/twist the throttle and you go, (tho you can still pedal normally).
E-Bike; with crank rotation sensor, you need to only rotate the crank and
don't actually have to put much pressure onto pedals and you go, (tho you can pedal normally).
E-Assist; with pressure sensor in hub axel,
you go nowhere, unless you pedal the bicycle normally... 
Just like riding a normal bicycle with a wind at your back.
10Lbs pressure onto the pedals gets you 3.5Lbs of pressure added onto your ten pounds of effort on level 1, if you only put
1Lbs pressure onto the pedals you will only get 0.35Lbs of assistance added to your one Lbs of effort...
TOTALY different from a crank sensor where you would still get the 3.5Lbs when only putting in 1 Lbs of pedaling effort...IMO
