I think groove is only emptying channel for quench area. With groove you can make sharp gas stream to combustion chamber and you can direct that stream where you want. Sharp, high velocity stream will improve turbulence in combustion chamber.
If you make quench pad in wedge form, you actually lower velocity of quench effect. This is allmost same thing, if you add quench clearance.
This is only my opinion. Others, if you see this thing otherwise, tell your opinion.
