In a word, yes!

"set multiplot" just looks like the right thing when you want multiple
plots to one screen or file. The manual makes it look like that is the
answer:
"The command set multiplot places gnuplot in the multiplot mode, in which
several plots are placed on
the same page, window, or screen."

I was lucky enough to read the manual for "plot" and wee that it took
multiple files, each with the standard options for style and it just
worked. But, if you search the manual for "multi", you find "multiplot over
and over along with the repeated (and correct) statement:
"Remember to close the output file before next plot unless in multiplot
mode."  makes it sound like multiplot is the intended tool for placing
multiple data sets onto a single plot when it is actually intended for a
similar, but different purpose.

I wish the "set multiplot" section had something near that top pointing out
that 'plot "file1", "file2", ..." is another, possibly more appropriate
approach.
