The difference is that toppath: works on the input stack and jobfile: on 
the accumulated subpaths (normally in a job structure) ... in fact, both 
could work out the same but the top of the inputstack could be different 
... it's all a matter of experiencing, so

\usepath[jobfile:]
\setupexternalfigures[directory=jobfile:]
\usepath[toppath:]
\setupexternalfigures[directory=toppath:]

could have the best of both worlds.

toppath == dir of top of inputstack
jobfile == dir of current jobfile

maybe jobpath is indeed better (i'll change it and keep the old one for 
a while)
