question about bi-wired speaker termination

I have bi-wired Purist speaker cables running to my B&W 802's.   Two terminators at the amp...four terminations at the speaker (two red, two black).  Obviously the speaker cable wire has more girth and bulk at the two terminator amp end...before it breaks into four, slightly smaller wires at the four termination speaker end.  Here is my question:  Even though all four terminators are connected via my bi-wired speaker cable, would it make sense to jump the two black and jump the two reds anyway?  Wouldn't that "restore" the benefits of the bigger speaker girth at the amp?  I actually did that but am not quite sure if I what I am hearing yet. Any technical thoughts would be appreciated. I am simply trying to get the most out of what I have! thanks, Jim
