That made sense in the 2014 rules, when there were rules for the benefits of hiding that were distinct from the benefits of being invisible - you might be invisible, and therefore have advantage on attacks against creatures that can’t see you, and those creatures might have disadvantage on attacks against you, but that didn’t mean they weren’t aware of your location, which would require hiding (which would be easier to do than normal, since you needed to be unseen to hide). But now, the benefits of hiding are that you become invisible. So if becoming invisible doesn’t also mean enemies don’t know your location, then there’s no rules mechanism for how you can make your location unknown to enemies.
