Fox QR vs Bolt axle (38 and 36?)

Confused by this.  I've got a 36 with a QR axle. First time you fit you loosen the bolt, do up the QR, tight the bolt with puts the 'floating' section in the right place to adjust for this particular for and wheel combo.  After that you just do up the QR and it's all tight.

Looking at someone's 38 the other day they had the bolt up axle.  The one fork leg could be moved side to side slight over when everything was tight.  They'd tried a QR and said that stopped the movement but the movement was actually intentional to keep the legs parallel and prevent binding.  

This seems odd.
