Must be an aftermarket sail. Ssometimes rqcing sails are cut that way if there isn't a rule against it or a measurement penalty. The reason for it is because you can pick up a bit of extra area, also, the foot of the sail has a slight angle of attack and there is less wingtip loss from air dropping down. I wouldn't worry about it if it sets right and doesn't whack you in the head on a gibe!

The foot of the sail is cut "downward" in the direction from the luff to the leach creating a downward angle of the boom from the goose-neck to the aft end. I'm curious if this was a necessary design element and what sailing characteristic it addressed.
