Piston squirters were not installed for cylinder lubrication. It was for piston crown cooling.
By adding the squirters, the cooling effect allowed them to reduce the thickness of the top compression ring, since it no longer had to conduct as much heat away from the crown. This reduced friction and improved sealing.
