When dual wielding your weapon delay is based on the sum of the 2 weapons.
Your main hand weapon's Base D is used in the WS calculation. You off-hand base D is only used in the hit damage for that weapon, so the base D of the off-hand weapon has a very small impact on your overall damage.
So generally speaking, people use a high base D weapon in the main hand (which tend to have high delay), but then to reduce the overall delay they use a lower delay weapon in the off-hand to reduce the average
I.E. Blau/Sirocco THFs, the Blau provided the bulk of the damage, and the sirocco brought the average delay down and thus increase swing speed.
It's a pretty complex issue as you need to consider x-hit builds and off-hand DoT etc but generally speaking, a low delay off-hand weapon will increase your swing speed and your overall damage.
But in the example given in the OP, if the base D is the same then it doesn't matter which weapons goes in which slot.
