I don't see anybody claiming that.

It's possible that you forgot to swap sidebands.

No doubt!
What is being claimed is simply this:
If you generate SSB (either sideband) at 9 MHz
and mix it with a 5-5.5 MHz VFO
you will get the same sideband on either the sum (20 meters) or difference
(75 meters) mixing product.
It's not a function of the rig used,
or the time period,
or whether it's phasing or filter.
The math proves it.
