It means if you stop clicking you disconnect. It means you cant afk at all while wearing it.
If they used the client ping instead, they could have a much smaller threshold of like 3 seconds of server being unable to find the client and then auto tp you to safety.
Instead you have to have a time last maybe 10 + seconds which could lead to a death even if you disconnect.
Or if you forget to click for 10 seconds while still playing the game, you get pointlessly yeeted out of your content.
