Quick answer: Yes it does.
Longer answer: In your case, I don't think so. I noticed the receiver says it can take some of the channels and use them to bi-amp your speakers, but unless it is somehow disabling the passive network (crossover) in your speakers, you're pretty much bi-wiring which does nothing at all.
Now if you built a pair of speakers and used an electronic crossover and then bi-amped....that would be totally different!
