Vita didn't become Nanoha's friend after being blasted. Nanoha never actually defeated Vita in battle before the Wolkenritter "switched sides".
Teanna was already technically on Nanoha's side before getting blasted, even though she was being insubordinate; which was a problem that didn't go away after being blasted, or being punched by Signum. It was Shari sharing Nanoha's history that won Teanna over.
Dieci didn't become Nanoha's friend after getting blasted; they've had next to no interaction with each other at all after that fight.
Quattro not only didn't become Nanoha's friend after getting blasted, she remained unrepentent and chose prison over reform. And she was hit harder than anyone else previous to that point in the series, which absolutely wrecks this theory.
Finally, Vivio was already won back over before Nanoha's final blasting. A blasting which *Vivio herself asked for*, in order to free her from Quattro's control.
In short, Nanoha has only ever "befriended" opponents into allies twice, it never happened that way again, and it had absolutely nothing to do with the firepower involved.
Therefore, this "Truth" is merely airheaded fanon.

Probably right, though.
