When single Hydra-pod equip on heli, 1 click 2 shots

When equipping only a single Hydra pod in the helicopter weapon customization, two rockets are fired with a single click.
Is this intended behavior?

I first noticed this during a test flight of the AH-6M, and then tested other helicopters as well. The same issue occurred on all of them.
I have confirmed that this does not only affect Hydra rockets, but also other rocket pods in general, such as the Soviet S-8KO.

When rocket pods are equipped on both the left and right pylons, one rocket is fired alternately from each side per click, which seems normal.
However, when only a single rocket pod is equipped on one side, a single click causes two rockets to be fired at once.

Thank you.
