I thought so too - and the forks are closer to an inch shorter.  
However you are changing triple clamps, and I have to believe there's  
a rake/trail change as well. So despite losing an inch of ride height  
up front the optimal shock length turned out to be the same.

As to why possible suspension changes, it's easy - preload and overall  
length change loaded ride height, and front/rear ride height changes  
how it steers. After changing the shock (and dog legs, an interesting  
idea) and forks/triple clamps you get the chassis geometry correct by  
adjusting ride height. But then you already knew that... (grin)
