Yes..that serves the same purpose.
You should have a steel cable, called a stay that attches there, and goes up the mast..the further back ypou attach the stay, the more the mast tilts back providing more rake, better pointing, but less downwind preformance, and also more weatherhelm. The opposite on the front hole.
Then the other one behind, is where you attach the clew of your jib.
If you tension the first one yo point better, but less forgivness, if you tension the second, you move sail draft.
