Do they disagree with the idea that P-P can completely cancel even

I may be wrong but I thought P-P intrinsically *only* produces even
ordered harmonics.


You do have it wrong. P-P intrinsically *only* produces odd ordered
harmonics.


Assuming perfectly matched devices in a perfectly balanced arrangement.

However any lack of perfect symmetry may mean that some orders are reduced,
but not removed entirely. Hence in reality you can expect a reduction, but
not a complete removal of the relevant components. Against this, the other
orders may be increased.

Slainte,
