what you've described, as far as i can tell, is correct. each "end" of rope should have a figure eight loop, those loops should be interlocking, and your rigging hardwear (biner, mallion, whatev) should go through both loops.
if the anchor fails (carabiner breakage is as you mention probably not likely, but if it's a bolt, the bolt could pull out, etc) you WILL get some rope-rope rub, but it will not likely move much due to the load on the rope.
it beats the alternative of not having the ropes joined...
