Bad heat treatment, or is it safe?

I have zero history working with this type of steel.
I do not own a sword with this steel, (Although it is next on my list to get..>LOL)
I have no knowledge of the differences between a steel I have worked a lot with like 5160 , 52100, and 1070 with what this person's 9260 steel.
I would never claim any "expertise" as to what this steel is exactly like to forge until I had forged it myself and could speak from experience.
Just like i would not try to review or comment on a sword I did not own myself and so could refer back to 'first-hand" knowledge.
I can speak from experience on the common blade steels as I have listed.
I have made and HT many blades with such steel.
I can speak about them as to what they were like for me to forge and HT...and the results I achieved.
The things in common between a steel I have worked a lot with like 5160 and this sword's 9260 led me to believe that they work under the hammer a lot alike.
Heat-treating?...Im guessing they are a lot alike based mostly on the amounts of carbon they have.
I also have read the accounts of guys who do work with 9260 and for the most part I cant see that what they are doing is all that different....
I think I saw a YouTuber video of a Chinese guy working on a 9260 and I did not see anyuthing in how he HT the swords he made that was any different in any big way from the way i heat treat a sword here...
But because I have never worked with that steel and gotten into the study of what things are actually different than my 5160 I cant say for 100% sure that goes for one, goes also for the other...
But at first glance that seem to have a lot in common from a bladesmith's point of view.
But as I said, it's not my steel.
Understand now?
so to review.
a common steel such as 5160 (and Im guessing 9260) is a forgiving steel, in that it is very possible to HT it a few times to get it right.
I actually know internet friends like Ed Fowler that teach that the best way to HT a blade is to take it to critical and quench it 3 times!
So the idea that you only would get one chance at HT a blade with 5160 ?
Well, all i can say is that in the real world things like multiple quenches and many HT are common ways some guys do stuff, and not really a big deal.
yes, some guys are better at quenching than others and get better results than others. and that is the help that experience gives the bladesmith.
I have also read in books about japanmese blades that over time have ended up in fires and then needed to be Heat-treated again to have a nice looking Hamon....and how to spot this because it will lower the value of the sword because the 2nd HT was not via the hand that first forged the sword.
