No no no.
startx sees the arguments _after_ all the shell muging (none in this case).
But startx is a _wrapper_ for two other programs - the X server and
your session script, invoked by xinit. Startx passes some arguments to
xinit and some arguments to the X server. The "--" tells startx where
the arguments for xinit end and the arguments for the server (":1")
begin.

It has nothing to do with the ":1" and everything to do with which of the

See the third paragraph of "man startx".
(Well, really, startx runs xinit with "nice" arguments - I always run xinit
myself - and it is in fact xinit which handles the --).
