Depending on motor/manufacturer its always exhaust or mag that the arrow points to so i am giving you a YES

Toward the exhaust. The easy way to tell if your doing it right is to mark the top of the piston at each ring locating dowel (just one if it's a single ring). Then make sure that point is not going over a cylinder port when your running the piston up and down. That ring gap will catch a port sooner or later if you have it in wrong.

Also on a 2-stroke the piston ring locating pins always go away from the exhaust port.
