ELI5 why do 2 note power chords sound good and resonate well on one guitar, but other two note harmonisations sound better on two guitars?

Intermodulation distortion from running an open fifth through a single amplifier is what actually produces the additional 'missing' notes to fill in a power chord. Playing each note through a separate amplifier doesn't allow for intermodulation to happen.
