If your modern stock coil sub-ohm tank has a good, non-defective coil that hasn't been compromised by accidental dry-hitting and burning of the cotton, and the recommended ratio juice is being used, then there is no reason why your coil should leak, even when you remove the negative pressure on the tank side of the coil's wick barrier, during refilling.
Shutting the airflow holes which are on the chimney side of the coils wick barrier, does not alter the air pressure on the chimney side because the chimney side is still open to atmosphere through the chimney itself. So, you might ask, what does closing off the airflow holes during refilling actually achieve? Well apart from actually holding back any leaked juice from exiting the tank until you open them again, absolutely nothing.
So to say it is good practice to close off your airflow holes when refilling is like saying "you must throw salt over your shoulder if you spill it" Just an old wives tale.
