But this assumes that you re-open the terminal driver before 
every plot.  That hasn't been my practice in the past, and I
suspect I'm not the only one with gnuplot scripts in daily 
use that don't do this.  The generic usage up until now has
been as below, and again I point to the demo scripts, not
because they are important per se but just because they
illustrate the scripting style.

    set term foo
 
    set output 'plot1.foo'
    set title "Graphs AB"
    plot "A.dat" title "A", "B.dat" title "B"

    set output 'plot2.foo'
    set title "Graphs CDE"
    plot "C.dat", "D.dat", "E.dat"

    ... and so on for many plots

I don't see the advantage in requiring that the terminal be 
re-opened between plots just so that the title is updated.  
If such scripts are not re-written, then under your suggestion
the page displaying graphs CDE will be labelled "Graphs AB".
