I think the OP is referring to phase. Starting with sine waves,
depending on which phase each harmonic is, as you add odd harmonics the
resultant (for a given fundamental) can be made to move towards either
a square wave, or a triangle wave. Whereas if you add even harmonics
you move towards a sawtooth wave.
To me, square and triangle waves sound identical at the same RMS
amplitude. However, the triangle shape will overload an amplifier
faster, and noticeably change in character, while a square wave hardly
changes at all until you are into severe clipping.
Obviously the situation is far more complex with 'real' sounds :)

Mangle ? How ?
Can't you just listen and see? (I don't know that I could. I may try a bit
later.) You seem to want theory while he seems to be giving hands on answers.
(I would like the theoretical answers myself, but they may not be on the way.
Have you done the practical side and still don't see what he is getting at?)
Signals
of different frequencies cam't ever cancel each other.
No, but they can seriously mangle one another in an undesirable
manner. If the channel following the harmonic generator,
i.e. after the exciter plugin, is linear then this can't happen.
Ciao,
all the best,
