It's a place holder to get the absolute orientation in model C. You add it to the same model which currently holds the minifig. Don't forget to first select the minifig (so it's orientation is copied to the next insertion). When the minifig is where it should be you delete the tmp brick again (in ether it's model or from nested C).
ps: to end nesting mode use shift+n
Maybe I should do another tutorial/demo clip on the nesting mode besides the mpd tutorial I made a while back?
