You are both correct from a simple electrical point of
view it is quite pointless. However, I might point out
that rightly or wrongly, probably a substantial majority
of people with an interest in Hi-Fi would say that
Bi-amped systems sound better

But this isn't really bi-amping. There are still passive crossovers, and
both amplifiers have to amplify the full signal.

and indeed to be
"pointless" the amplifiers would have to suffer zero load
issues.

Note that the impedance curve of this speaker shows that the tweeter
provides only a small fraction of the load on the power amplifier.
