The practice is to have both ends of individual lines connected to the boat so one can readily disconnect from the moorings.
Anytime you're connecting to something you might need to disconnect from while still in your boat, a good practice to just loop through it and have both ends tied to the boat. We observed but didn't use the San Francisco Bay double bouys.
