  first colum and last row active??

I'm working on a project using porvay, and am currently looking through the
"Start_Adaptive_Tracing" method and inside the loop (over columns then rows)
there are two for loops which are commented as setting the last row inactive and
setting the first column inactive.

I was just wondering what these actually do as I'm a little confused by them?
