I'm not to keen on the technical portion of it but lets put it in laman terms, the shortest distance betweeen 2 points is a straight line.

If the distance between both GPU chips is shorter on X2 versus 2 cards there will be a performance boost, we see this in benchmarks already.

Shorter paths, less resistance = gain.

They implement the same philosophy on reference boards. Grouper, manta and the 790gx amd reference boards all had the PCI X at the very top slot almost touching the NB and the NB was oriented very close to the CPU. It's done intentionally.
I didn't even think of that. well also isn't it cheaper to make since it's one PCB,
