In order to dual wield the spells so you gain the advanced version, both controls have to be pressed at the same time, when it is the advanced version (destruction) it is obviously different. However, there is no point dual wielding unless you have the dual wield perk, as you are treated as having one spell equipped and do not get extra dmg using both hands. Will also add here that attempting to dual wield identical weapons messes up favourite assignments, just apply an enchantment to one so the system sees them as different.
As for equipping, there is a graphical bug that will only show one hand equipped if you switch both hands too quickly, just use the mouse wheel to scroll out and you should see the effect coming from both hands.
