I'd say no. It likely works by storing your validation in a session on the piclist.com server. It'd also have sent your browser a cookie which'd have a value which would uniquely identify that session. All subsequent requests you make would send back that cookie, the server would look up that id to get that session. So the other computers using it wouldn't have the cookie so they couldn't be linked to your validated session.
