Huh?  No it doesn't.  It expands to
      plot "a.1.dat", "a.2.dat", "a.3.dat", ...

So each plot gets a new line/point style.
I know it works, because I actually tested it using the short script
in my previous Email. An even simpler demo of the principle is

gnuplot> plot `demo.pl`

where=20

#~/usr/bin/perl
# demo.pl
  print " '1.dat', '2.dat', '3.dat' "
