Yes, that's correct, the semicolon (followed by a space) is used to 
delimit the commands.

I think, Ralf means ". $HOME/.fehbg", the full-stop at the beginning 
matters...

But what's with the doubled autostart.sh ?
With the two subshells, you should have the parent process 
(autostart.sh) and,
for a short time, two sleeps in your process list, but not 2 autostart.sh.
With your new version, of course there should occur only 1 sleep.
