That cut looks like it goes right through the cords. And, yes, I've seen cuts like that zipper open. With a cemented boot in place.
The problem is keeping the tube from protruding which a boot should handle. I would use it for a winter tire.
The other problem is (If the cut is in fact through the cords), that any significant change in tire pressure (ie, running over a rock or something) will cause the tire to zipper open.
Of course, there's lot's of times where the "fugetaboutit" technique will last a long time, even in a part that is borderline failure.
