When I look at the bike, the handlebars are bolted stationary onto the bike. They don't turn the bike.
Which means you need to turn the bike with weight. Not by pushing the bars.

you use your legs as leverage on the tank and pegs.

the bars are there like that as a faux hand position, instead of making the rider use no hands with no throttle or brakes.

I may not be coming across correctly, but I very well understand the concept of that bike with the fixed handlebars. That bike is trying to teach you that you DO NOT need to turn the bars to corner a motorcycle. You use your weight. Your weight turns the bars.

Try riding that thing and seeing just how scary it is. I practice this myself, but I just use no hands while going down hill so I don't need throttle. I hang on to the sides of the tank with my hands, slow down a bit and go around turns with no hands, using only my weight.

It's very scary. Teaches you a ton very quick.

IMO, that is proper positioning, not countersteering.
