I am often asked whether you need to grip the club with the trail hand to match your trail arm action alignment.  In other words do under golfers need to grip it with the Under Alignment that matches their Under Trail Arm Action alignment?  The answer is know.  It is a good place to start but not an absolute.  For example Rollers typically grip it weaker (more on-top) than their neutral alignment.  There are many reason why your trail hand grip alignment may not match your trail arm action alignment.
