Why shouldn't I bi-wire Wilson Watt/Puppies 6

I just aquired a pr of WWP6's and saw in a review that "Wilson will void the warrentee if one bi-amps or bi-wires these speakers". I have a pr. of bi-wire Nordost SPM reference that I would like to use but this has got me scratching my head. I just set the room this morning using a pr. of Cary 805b amps. The speaker wires are plugged into the 8ohm and 4ohm taps on the Carys and then bi-wired to the Wilsons. Nothing has been turned on yet as I had to go to work, (where I'm writing this from;-) If anyone can enlighten me as to any possible problems from this setup, it would be appreciated. I don't want to have to wait to talk to Wilson on Tues before playing some tunes!
