I want to believe stuff like this, but the whole field is so mired in quackery and jingo it's hard to believe any of it. A PT with a radical personal theory, plus some youtubers and instagram influencers hardly inspires confidence. At least there are no doctors writing pop health books! But some studies in some scientific journal would be great.
That said, holding stretches longer and focusing on relaxing while stretching hardly seems risky, and could be worth a try.
