That's right. Having too wide of a chain can lead to slipping, since the wider chain can catch on the teeth and jump, but having too narrow of a chain could only lead to poor shifting (I've run narrow chains on 5-speeds without issue many times). There's no plausible way to have too wide a chain on a 5-speed.
