The great thing about gliders is that you can't go around.
Therefore, in this scenario a "land after" even if not strictly legal has to be LEGAL because of safety issues. It would take a lot of aurguing to say you were in the wrong if the only other choice was to put down in the rough! If it went pear shaped I suppose you might get in trouble ... but then if landing after was a good option but you didn't take it and crashed you'd be equally at fault.
