Maybe its turned up for better (deeper) penetration. The turned down eye does close the gap, slightly. With a toothy fish, this could be a problem.
I also think the barb's height closes the gap, I think the barb should be cut on the outside of the gap along with a straight or up-wards turned eye. This would allow maximum hook gap to be utilized with each hook.
Just my .05¢ worth, it was .02¢ before inflation.
