What do they claim? If you stroke it more than 3 times, you're playing with it?
Not so, for some people it takes more than that, just to get all the urine dribbles out. It takes what it takes. But a urine-removing stroke, is likely visibly different than playing with it, and it shouldn't take too long either.
I think I have to stroke it a few times, to squeeze all the urine out. So detestable to get those embarassing wet spots in one's pants.
