If I understand the problem:

Orientation of line has essential importance in Therion. Normaly, everything what is on right side of line wall as you draw it is bedrock (if you don’t define colour map-bg it will be white in PDF). The reverse command has been added later just need not to redraw the wall with correct orientation. Before that only way was to delete such line and redraw it. Normaly the line wall has empty space on side of yellow tick, bedrock on oposite side. 

Outline is by default defined only for wall. You may use -outline in or -outline out for other lines as well. 

In your case you has two scraps. Upper scrap ends with pit. If you don’t define outline Therion will connect ends of passage and there will be red sickle and part of little ticks of line pit will be clipped.

If you use for line pit -outline out and -clip of Therion will use this line as line wall and clip everything on oposite side as yellow tick is. Clip of means that small ticks, part of symbol line pit, will not be clipped. 

Because you has second scrap under the first one it willl look as the end of first scrap after pit is transparent.
