If you check the 'save' vid, in slo-mo Andres, you can clearly see just where
the rider backs off the throttle, then winds it back on, to straighten up,
(as a needful inertia-control input function).
There are many complicated inter-related dynamics involved in cornering a
one-track vehicle, & any scenario may develop unexpectedly - yet must be
managed accordingly - via skilled responses involving proper inputs,
applied in a timely fashion, if a crash is to be avoided, no?
Sorry to say this JAW, but I was assuming you know how to ride a bike, but you´ve just proved the opposite!
Backing off the throttle is very different to cut-off, when a powerslide goes too far you obviously need to back off the throttle as that´s the cause of the slide, but if you cut-off the throttle completely the crash is guaranteed at 100%, and it will be an ugly crash btw

one being the low 'engine braking' inertia of the 2T machine, when he cuts the throttle to stop
Talking about engine braking inertia of the 2T machine to stop a powerslide you´re proving you have no idea about controlling motorcycles, not even a vague idea!
To control a powerslide wich went too far you have to stop accelerating hard, but you cannot stop accelerating completely, or the wheel will bite the tarmac (I think in english this is how you say it) suddenly and you will crash. It doesn´t matter if big or low engine braking, if while powersliding you go from accelerating phase to decelerating, you´re done, period, no matter how small is the deceleration. Anyone with a bit of experience in motorcycling knows this, what is shocking is realicing you have no idea about controlling a bike at all, but even so you´re so vocal in this and other similar threads
On the contrary Andres, since if you actually watch the vid, you can see for yourself, what the
rider is doing with the movements of his throttle hand, yet plainly, he does not crash, which
shows he understands the dynamics situation full-well, & furthermore, if you'd had sufficient
hard/fast riding experience with powerful 2T & 4T bikes on a tarmac surface, you'd also have
a more realistic understanding of the engine inertia issue.
4T race bikes had to go to high off-throttle 'idle' engine rpm, then 'slipper' clutches, followed by
a sophisticated electronic control suite - to overcome the 'inertia drive' issue - on a cut throttle..
Back when 500cc 2T bikes were raced, no such electronic assistance was available, & it was
the mark of a championship winning rider that he had fine throttle control coordination skills.
