Unsetting the terminal is completely unnecessary.  You will have to 
close the plot though, i.e. "unset output".  gnuplot cannot  possibly 
write the closing tags if you didn't tell it you're done with writing to 
the file.

The reason for the difference is that JPEG only allows one page per 
file, SVG allows as many as you wish.

Absolutely no.  Not all loaded scripts end the output file.

Absolutely no, for basically the same reason.
