The piston is downstream of the master cylinder or hose that replaces it.
Think of it in this context, appropriately Americanised

: The master cylinder is a hopper, where you might pour a pile of bullets (or brake fluid). The master cylinder piston is the breech of your machine gun. The piston takes fluid (or bullets) from the hopper and pumps (or shoots) them down the brake line (or barrel). While the bullets arene't needed they just sit there in the hopper, waiting their turn. Difference being, with a brake, more bullets only come out to compensate for the brake pads wearing. So, you really only need a small amount of fluid waiting upstream of the master cylinder. I wonder if that makes any sense at all?
Edit: just looked at the pic of the scrambler: It's a radial master cylinder so a bit different execution but the idea's the same.
