Yep. Even if you put down a pink it will only exist to get rid of a ward and won't be a reliable peice of vision in and of itself so you'll have to lay down a pink ward and then a normal ward. Luckily you can only have one pink and the sightstones never run out so in general unless you need a gank there's no reason to de-ward the lane with a pink.
