Is this really working as intended now?

I just did a 10 minute test on level 90 training dummies with the ingame stopwatch going.

It procced one time at 1:55 seconds in. Didn't proc again after that.

According to wowhead it has a 55 second ICD so it should have procced multiple times during my 10 minute test.

Whats the deal?
