Havok’s prowess charges (from heavy attacks) remaining after special 3

In Havok’s abilities page, the 5 prowess charges he gains from heavy attacks are descibed as “lasting until Havok’s next special attack ends.” This does not seem to function with his special 3, meaning he retains the 5 prowess charges after his speical 3 ends.

Just looking to find out if this is intended or not.

Here’s a short video of the 5 charges remaining after special 3 and not being consumed until he uses the special 2.

Any input? Am I missing something? The +50% prowess you can carry from a special 3 into other specials without having to build it back up makes a big difference on his output.
