It simply adds fiddly bits to provide a 510 connector rather than using the
mod in its native hybrid mode. Ohm's Law applies in the same manner regardless of your physical atomizer connection.
Using the mod in its intended hybrid mode is perfectly safe as long as your atomizer's 510 protrudes a sufficient distance from the negative 510 connector... and assuming it's not a spring loaded pin which will get pushed up into the connector when you fire it.
