I am merely guessing here, but it is either something to do with making a racing rating, or it is perhaps cut that way to avoid snagging on the shrouds or the spreaders when close-hauled and/or tacking tight angles.
I know when I shredded an admittedly old light No. 1 when I came around a point of land and the wind went from 10 to 25 knots, it was the leech line that hooked on the spreader and started to tear the sail at a right angle. I had to cut the leech line to release tension, because letting the sheet slacken didn't free the sail. A "hollow leech" in such a situation might have avoided this issue, but then again, that particular sail owed me nothing.
