The video suggests a solid website not base on SEO gimmicks will stand up to Google scrutiny
If by scrutiny, you mean manual review, then it's just a pity that so many decent sites don't ever get that kind of manual review (aside from being manually reviewed strictly vis-a-vis off-page signals that they may or may not be responsible for).
Candidly, no. My quote (on Google's quotes) implies if your website was "that good"... you wouldn't need Google to do anything because someone else was delivering you ill will... as the ill will wouldn't work. At worse, you would see a temporary gain and a lose of that gain... nothing more. At best, you would get the gain and never lose it. If you are not responsible for the off-page signals those signals generally didn't produce your stable ranks.
The problem with (example only) a marginalized domain, they aren't all that compelling to foster good will (natural links) so if the difference between top results and bottom results is ill will... your own limitations to foster that good will are the compelling reasons for your decline.
I've seen numerous false positives over my time but Google is fast to correct those thus any reluctance to demonstrate to Google any false positive remains your responsibility.
In short, "you can't fix what you can't find!"
