IMO, I don't think it's a problem at all. If you've glued DHS Hurricane before you'll notice if you put the words in the center, the rubber itself will be off center, i.e. if you cut the rubber like that, one side the leftover rubber will be a lot thinner than the other. So I'd say if Tibhar makes their rubber like that as well, you might see this happening. But as mentioned above, this doesn't affect the feel at all, manufacturers put those words on there because you're not supposed to be hitting the balls with that part if you're doing it right.
