A full western Grip is used for people who want that ridiculous top spin like nadal. A continental grip gives you back spin / slice(serve). For volleying the continental grip is used because if done properly you will push out to the ball so the ball is flat with the same or more amount of pace from the ball you returned. Also it is used because many balls you are returning are at the level or possibly below the net, so you will have to open your racquet face up to make sure the ball gets over the net, which the continental grip already allows you to do and the western does not, in fact the western grip would be face down which would cause you to hit it in the net. Plus this would extremely hurt your wrist tring to hit a western grip for a volley
On a volley, you want depth and a bit of backspin on the ball so that it stays low and is difficult to return. With a continental grip, it's easy to do both. It's difficult and sometimes painful with a full western grip, and it's almost impossible to get depth on the ball.
Also, if you keep a continental grip at the net, you're already prepared for a backhand volley. You don't need to change grips. It's pretty much impossible/not worth hitting a backhand volley with a western grip.
When the ball comes at you low, it's simple to get down and scoop the ball up, so to say. With a western grip, you'd probably break your wrist or pop the ball up high enough to get murdered.
The only benefit of using a western grip is to get topspin on groundstrokes. That's it.
The answer is simple - when you play on net you have not enough time to change grip and you must to choose one universal (continental) grip that is not the best but is suitable for all shots on the net. Of course if you have enough time you can use the grip that you prefer
