Intended? probably not. But why would you issue such a command?

Expected? Yes.
Each replot command repeats the previous plot and adds 
a new sin(w*x) to it, so there is one additional curve
each time through.


"help replot"

 Arguments specified after a `replot` command will be added onto the last
 `plot` or `splot` command (with an implied ',' separator) before it is
 repeated.  `replot` accepts the same arguments as the `plot` and `splot`
 commands except that ranges cannot be specified.
