Yes. Over tightening can cause damage to the lockring from stripping threads to causing cracks. Under tightening can cause the lockring to come loose or undone while riding but you'll probably notice the crappy shifting from a loose lockring before it comes undone which could possibly cause your chain to get jammed into some part of your drivetrain. But, I'll say again that these have a lot of room for error before you need to be concerned. Anytime I mount a cassette I'll give it a quick check after the first ride to make sure it's tight. Probably overkill but that's just me.
