some quick experimenting in game points to 2 casts per cooldown peroid

use 3 skills, you get 8 mana

use 2 skills, you get 8 mana

use 1 skill, you get 4 mana

wait until it the item icon says it's cooled down and use 2 skills again, and you get 8 more mana (not 100% certain on this one, as my shortest cooldown skill when testing this was just over 6 seconds, so the 4th cast wasn't until almost 7 seconds after the first. 3rd cast was immediately after the cooldown)
