When reading that primer it's saying something about what happens when you get interrupted that looks backwards.
First, you stop casting the spell or activating the skill you were trying to use. You also lose the Energy or adrenaline cost of that skill. The skill does not incur its recharge time, however, so you may attempt to recast a spell immediately after interruption. Keep in mind that you do have to wait for aftercast (the one-second delay after casting a spell in which you cannot cast another spell) to expire before recasting. The same effect applies if you get knocked down while casting; you still lose the Energy cost of the skill.
As far as I know, normal recharge applies, and there is no aftercast from the interrupted skill.
Unless they completely changed how interrupted skills go.
