It is not a question of what terminal came before,
but rather a question of what happened after.
(unless, of course, there is indeed a bug we don't know about)

Yes. This is known, well-documented, and basically could
not work any other way.  But it doesn't have anything to
do with wxt.

It is the same with PostScript, and with any terminal
type that can produce an output document containing
more than one plot.  PNG is not an example, but this
would also hit I think SVG, MIF, PDF, etc.

OK. At this point you have opened an latex file and written
one plot to it.  The program does not know if you are going
to add any additional plots, so it still has the file open and
has not yet written the close document statements.
At this point the end of the *.tex file looks like this:
    \gplgaddtomacro\gplfronttext{%
      \csname LTb\endcsname%
      \put(5971,4603){\makebox(0,0)[r]{\strut{}sin(x)}}%
    }%

If you now do

or
> gnuplot> set output ... anything

The program now knows no more plots will be written to the
previous output file. So it finishes off the previous output
file and closes it.  At this point the end of the *.tex file 
looks like this:
    \gplgaddtomacro\gplfronttext{%
      \csname LTb\endcsname%
      \put(5971,4603){\makebox(0,0)[r]{\strut{}sin(x)}}%
    }%
    \gplbacktext
    \put(0,0){\includegraphics{good-inc}}%
    \gplfronttext
  \end{picture}%
