Emh no, volley fireing was used when big smoke clouds caused your blindness and your aiming, it was much easier to fight in windy weathers since the smoke disapeard faster then. This is something you can figure out yourself really.
If 50 men are fighting in a line and one of them put a shot up to the enemies the smoke from the gun will block about 2-4 of the other guys sights, that's why repeatedly fire couldn't be used. This is atleast how the Swedish fought, I don't know if the other ones had magic muskets which didn't puff out smoke when fired, if so I'm sorry for being wrong.
It didn't matter how you shoot, you'll always get smoke. In a Napoleonic fire-fight (in which time the muskets made a bit less smoke (I thought) than earlier), soldiers could see
nothing anymore after a few volleys due to the smoke ; some of them said they only knew the enemy was still there because the Sergeants were constantly pushing replacements forward when soldiers fell.
Firing in volleys was invented because it had much more effect than a single shot, as muskets and arquebuses were notoriously unaccurate, and a volley would hit the enemy harder than single shots.
