I think its likely a built in mechanism so you can't just be like Cardia explosion on someone.
Pneuma is stated as a 'spell' in the tooltip.
All spells are on the GCD.
The 1.5 sec cast time also supports that theory. It just has a separate cooldown unique to the skill in addition to being on the GCD.

Abilities on the other hand, are oGCDs. Actions listed as an ability like Icarus or Physis II are on the oGCD.
