In case you want your question answered and don't want to do the research, I will attempt to give my definition based upon my understanding of Bi-Wiring. I must preface this with a sincere appology to all experts that will undoubtedly find source of critizism in my definition.
I beleive that the benefit of bi-wiring is that a seprate run from the amp output allows the frequencies to seperate according demand. So the highs and mids seperate themselve from the lows. I think it is more beneficial in speaker wiring that has multiple sizes of wire strans within a cable. The smaller guage wire seems to be more condusive to the highs and mids as these frequencies run at a higher frequency of vibration and the low frequencies seem to travel better on a thicker guage wire. I have done both shotgun and regular bi-wire and can say the I (me personnally no scientific proof) can hear an improvement.
When shotgunning I think you can actually gain if the wire is all of one type or similar guage. I have done a shotgun with two brands of the same guage and found one brand to enhance lows and the other enhanced the mid/highs. Right now I am using a 8 strand 6 guage wire that was purchased as a bi-wire and it seems to benefit the sound as well.
One acid test is to jump them together at the speaker and listen for a difference. One think that is true is this a heavily debated subject and opinions are all over the road.
My suggestion is if budget allows is try it. It all comes down to your system and ears as the final judge.
Again just my opinion here, not claiming to know anymore than any other reader here.
