I guess its the placement of padding space, when formatting fully
justified ASCII, that's puzzling you?  AIUI, to avoid rivers of padding
space, groff alternates, line by line, between insertion of such space
from left and right ends of successive lines.  Insert an odd number of
lines, and you swap the left vs. right effect on subsequent lines.
