Nice article.

A quote from the article you linked to:

"The most common question I get is ...

"Do I need to disconnect the passive crossover in my speakers?"
The answer is ... Yes, otherwise you are not really biamping at all."

This why we say you are not Bi-Amping at all. The process of removing the shunt bars on the back of the speaker terminals and then running the amps with the passive crossovers still in use but split appears to called passive biamping by many.
