Well, the opposite is wide swing a lane ur team doesn't control. If you do this, you'll need to clear many positions at the exact same time, and you could be taking a duel with multiple enemies all holding ur position. You lose these as they're in the enemies advantage.
A better way is to always clear individual positions when you swing, to swing more narrow so you can only fight a 1v1 if you see someone, to swing as far as you can from corners as possible, so you see enemies before they see you, and to use utility to clear positions you're peeking. If you use util to clear angles, you just avoid the duel or have something you can swing off of.
