I'm afraid combining data from two sets like that is going to be 
impossible with the data residing in two separate input files.  With the 
data in a 3-column file, something like

plot 'file.dat' u 1:(max($2,$3)):(1+($2>$3)) w boxes lc var, \
              '' u 1:(min($2,$3)):(1+($3>=$2)) w boxes lc var

might do it.

I therefore suggest you use external tools like the classic Unix 
utilities 'join' and 'paste' to turn your two files into one, before 
attempting to plot this.

Let's just say that putting the two data sets besides each other (i.e. 
using slimmer boxes, with a bit of horizontal displacement) would be a 
whole lot easier than trying to force gnuplot to do it your way.
