Demoralize - a bug or not?

I spinebroke someone today and use the demoralize skill on him. Then I noticed in my own effects that I had the "physical malady" demoralize for 15 hours or whatever it was. Is this merely the timer until I can use the skill again? Because if that is the case I was a little surprised that it was shown in my effects as a physical malady instead of a skill. I can understand if it has to be shown as a malady in my affects because it is a malady in the victim, but I just wanted to check that it is working properly.
