They are sticky, but the stickiness is more fine-grained.
Try thinking of the command not as "set label" but as "set label N".
It permanently changes the properties of an object (label N) for 
all future plots that it appears in.  So
    set label 4 "I am the fourth label" font "Times"
    set label 4 at 0, sin(pi/2)
    plot sin(x)
    # Now that I see the plot I hate that font!
    set label 4 font "Arial"
    replot
    # That's better, but let's try right justification
    set label 4 right
    replot

If you want to change some property for many labels in parallel,
one option is
   set for [N=1:100] label N rotate by -45 
Note that until you assign a text and location for a label it will
not appear in a plot.

Other set commands work the same way:
	set linetype 3 <whatever>
	set object 4 circle <circle properties>
	set arrow 2 <arrow properties>

Hmm. Good to know.  We can try to make it easier to find in the docs.

Could it be that you are looking for the "replot" command?
Coincidentally, you could type this as "repl" :-)

1) Choose an interactive terminal (x11, wxt, qt, domterm, sixel).
2) Issue your plot command 
3) tweak any of the setting for fonts, linetypes, margins, etc
4) "replot"
5) rinse and repeat
6) when you are happy with the plot, either use a menu button to
   save to file (wxt qt win) or change the terminal type and
   again "replot".  E.g.
   set term pdf
   set output 'final_version.pdf'
   replot
