That expectation fails because you assume 'w' to be expanded during
command construction.  It's not What you actually created was

	plot sin(x)
	replot sin(w*x)
	replot sin(w*x)
	replot sin(w*x)

which is, not coincidentally, also indicated by the legend entries: the
2nd to 4th entry all say "sin(w*x)", because that's what you're plotting.

To get what you actually wanted, you should put that loop _into_ the
plot command:

	plot sin(x), for [w = 2:4] sin(w*x)
